Stellaris has 124 different Steam achievements. Achievements have no in-game effects, the achievement just pops up in-game and then added to the player's Steam profile. It is possible to see the achievements sorted by the percentage of users that managed to complete each achievement by going to the game's global stats at Steam.
The difficulty of each achievement varies; some achievements are very easy (e.g. colonizing a planet), while some are extremely difficult (e.g. end-game crisis achievements). The below list groups the various achievements by a difficulty level as assessed by the wiki editors (uncategorized - UC - achievements haven't been assessed yet).
Achievements can only be gained in Ironman games. They can be earned while playing older versions of the game as long as said achievements were present in that version, as well as after any empire has attained victory.
- Using Settings can make several achievements easier. In particular, setting the galaxy to have no other AI empires (besides Primitive Civilizations) prevents spaceborne aliens from being killed by AI empires; this is useful for getting the "Warrior of Light" achievement as wraiths tend to wander the galaxy.
List of achievements
The "Ver" column indicates in which version a certain achievement was added. Achievements cannot be earned prior to the version they were added in.
The "DI" column is for difficulty as assessed by wiki editors. VE = Very Easy, E = Easy, M = Medium, H = Hard, VH = Very Hard, I = Insane, UC = Uncategorized.

|Have empires representing every ethic (it can be fanatic or normal) in your Federation||It is easier for the player's empire to change their own ethics when already in a federation with five unique ethics from other empires. The Federations DLC allows overcoming the federational invitation process by vasalizing empires with the subject joining law on yes.||2.6||M|
|Has terraformed a planet into a Gaia world||Gaia Worlds created by events also count||1.4||M|

|Has completed a precursor event chain and travelled to the subsequently revealed system||Starting the game with no AI empires makes getting this achievement a matter of time||1.4||M|
|Have 100 Intel on five different empires at the same time.||The Sentry Array (Megastructure) elevates your passive Intel level by 40. It is easiest performed by building the Megastructure and then releasing 5 vassals.||3.0||H|
|Has invaded Earth, found in the Sol system, while it is in the machine age. Earth must spawn already in the Machine Age, not reach it via event or progress over time.||Sol has a 50% chance to spawn regardless of galaxy size if no empires have it as its starting system, therefore it is recommended that a tiny galaxy be used to make it easier to find and claim the Sol system. If it spawns, it has a 25% chance of being at the correct era for this achievement, for a total chance of 12.5%.||1.4||H|
|Have total Pops > 200 and 75% of them as robots||Best done by going for Synthetic Evolution Ascension Perk||1.4||H|
|Either go the route of building one, repairing one or capturing one from a Fallen Empire.||This achievement is disabled by the Shattered Ring origin.||1.4||H|
|Has completed the In Limbo anomaly either after having researched synths, or prior to accepting an enigmatic observer fallen empire's relevant request following.||See Limbo for event chain details||1.4||H|
|Number of different species on a planet > 10||Best done by resettling Pops obtained from Migration Treaties or conquests or by conquering The Preserve from an Enigmatic Observers Fallen Empire. Curiously, as Driven Assimilator you can conquer a planet with at least five species because organics and cybernetics are counted as separate species.||1.4||H|
|Has chosen and completed the project to lower the barrier on a shielded world||Shielded worlds appear inside the borders of the Militant Isolationists||1.4||H|
|Be a Xenophile or Fanatic Xenophile empire and have migration treaties > 10||Easiest done by releasing as many 1-planet vassals as needed towards the end of the game||1.4||H|
|Colonize 4 worlds with the Holy World modifier||Best strategy is to have the Scion Origin story and be a fanatic spiritualist empire. You will start with a spiritualist Fallen Empire as overlord, with the required Holy Worlds within 10-20 jump of them. Since you are their vassal they will allow you and only you to colonize them. Turning off AI empires helps speed this up. This same effect can be achieved if the Head of Zarqlan Relic is obtained.
Alternatively, you can get the achievement as long as there is a Holy Guardians Fallen Empire and you take over and start to colonize the nearby Holy Worlds.
|Destroy the Contingency Secret Lair||Like all crises lowering setting the Crisis Strength setting to 0.25x makes this a lot easier to achieve.||1.8||VH|
|Has captured the Prethoryn queen||Like all crises lowering setting the Crisis Strength setting to 0.25x makes this a lot easier to achieve.||1.0||VH|
|Destroy the last Extradimensional Invader portal||Like all crises lowering setting the Crisis Strength setting to 0.25x makes this a lot easier to achieve.||1.0||VH|
|Has found a way to stop the synthetic infiltration||Complete the event chain to detect synthetic infiltrators during the Contingency crises.||1.0||VH|
|Has completed the Horizon Signal event chain and either outcome||Accepting the Worm's offer is the easier choice||1.4||VH|
|Has purchased a scientist from a curator enclave after having developed sufficient opinion with them to do so||Even though the Curator Enclave appears with Distant Stars as well, this achievement requires the player to have Leviathans||1.4||E|
|Has chosen to become a patron of an artisan troup enclave and waited 10 years for the initial energy credits payment to expire||This achievement appears to be bugged and will not always unlock properly.||1.4||E|
|Has purchased a strategic resource from a trader enclave||1.4||E|
|Has destroyed an enclave station||It is recommended to destroy an artisan enclave if going for this achievement, as it will not incur a negative opinion penalty with other empires, unlike the other types of enclave, and to also keep in mind that such stations generally possess ~8k fleet power.||1.4||M|
|Has defeated the Automated Dreadnought and chosen to repair it||See the Dreadnought main article for information in how to defeat it.||1.4||H|
|Has defeated the Ether Drake, placed a mining station on Dragon Hoard and chosen to incubate the dragon egg once the event fires||The MTTH for this event is 600 months after the mining station is placed. See the Ether Drake main article for information in how to defeat it.||1.4||H|
|Has peacefully completed the Infinity Machine event and, by luck, resulted in the black hole gaining The Mirror Of Knowledge modifier, among other things||Agree to assist the Infinity Machine (must not be Gestalt Consciousness) and complete the 1800 day special project "Understanding Infinity". When the project completes the game randomly selects the outcome and the desired outcome of success with the modifier required for the achievement has a 25% chance of occurring. The other results are a 50% chance of failure and a 25% chance of success with no modifier (i.e. a 75% chance of an outcome that does not obtain the achievement). If a successful result is obtained the specific type of success is still hidden from the player and not revealed until the Infinity Machine enters the black hole and the screen showing the rewards appears.||1.4||H|
|Has defeated the Stellarite devourer and chosen to make it a trophy (requires xenophobe or militarist ethics)||See the Stellarite Devourer main article for information in how to defeat it.||1.4||H|
|Has successfully defeated and completed the event chain of the Enigmatic Fortress||The Enigmatic Fortress article contains a guide to complete the event chain||1.4||H|
|Has defeated the Spectral Wraith||See the Spectral Wraith main article for information in how to defeat it.||1.4||H|
|Has taken up the position of the Leader of the League of Non-Aligned Empires during a War in Heaven which has then defeated both awakened empires.||Best time to go for this is when a crisis is happening at the same time near an awakened Fallen Empires. Requires you to be the leader when the war is over, and since the League starts with rotation, you may need to wait to finish the war or change the League's laws.||1.4||VH|
|Has defeated the Dimensional Horror||See the Dimensional Horror main article for information in how to defeat it.||1.4||VH|
|Has >499 pops under Utopian living standards||Even though Utopian Living Standards are available in the game without the Utopia dlc, this achievement requires the player to have it||1.5||M|
|Any owned Habitat in a system with a Black Hole||Achievement does not trigger on stars that were turned into black holes by events||1.5||M|
|Is a hive mind and has >999 Pops.||Only the overall amount of pops in the empire is checked for this achievement, so conquering pops of any species with or without the hive mind trait, will help in getting this faster||2.2||M|
|Has > 4 species enslaved as Livestock.||The Syncretic Evolution provides one species||1.5||M|
|Has unlocked the Transcendence Ascension Perk and entered the shroud||1.5||H|
|Has constructed a complete Dyson sphere||A repaired destroyed Dyson Sphere does not count||1.5||H|
|A species has > 7 trait points||Requires the Evolutionary Mastery Ascension Perk||1.5||H|
|Has 4 completed Megastructures.||Repaired destroyed Megastructures also count, which can be useful if you lack enough DLC to get 4 normally.||2.2||H|
|Has constructed a complete Sentry array||A repaired destroyed Sentry Array does not count||1.5||H|
|Has unlocked the Synthetic Evolution Ascension Perk, completed the project, and converted all eligible empire citizens to synths||1.5||H|

|Has constructed a complete Science nexus||A repaired destroyed Science Nexus does not count||1.5||H|
|As a Determined Exterminator, have the number of organic empires be < 1||Curiously, the Determined Exterminator civic is not required to complete this achievement.
You will automatically obtain the achievement if you start a game with no organic empires (set number of AI empires, fallen empires, and marauders to 0).
One can also get this achievement after getting the "suffer not the aliens" achievement by switching to a synthetic species through the synthetic ascension path.
|As a Driven Assimilator, have 5 different cyborg species||Easily accomplished by conquering primitives. Setting Habitable Worlds to 0.25X and Primitive Civilizations to 5X ensures many systems will have primitive civilizations.||1.8||M|
|Has terraformed a planet into a Machine World||Two ascension perks are required to be chosen before the option to unlock machine worlds is made available.||1.8||M|
|Have the Rogue Servitor civic and >9 pops which started the game in a Fallen Empire||Refugee pops do not count||1.8||VH|
|Has destroyed another Empire's capital planet with a World Cracker Colossus||Custom empires with nothing but bad traits can be created.
Can be achieved by destroying a Contingency planet. Using one on a Fallen/Awakened Empire planet will also not give the usual diplomatic penalties with other empires.
|Destroy the Great Khan and his/her fleet in battle||The Great Khan is killed in battle when his fleet is destroyed or defeated in a battle twice.||2.0||H|
|Use a Global Pacifier Colossus to shield a planet belonging to a Fanatic Purifiers, Devouring Swarm, Determined Exterminator||2.0||H|
Stay on Target
Destroy another Empire's Colossus while it is in the process of firing on a planet.
|Destroy an enemy Colossus while it is firing on a planet||The process of "firing on a planet" includes both the preliminary three-month "charging" phase as well as the one-month "firing" phase. Fallen Empires can spawn with one Colossus, and may build one after awakening (the Spiritualist FE will immediately awaken if you crack a holy world). The AI will have its Colossus try to run away when you enter the system with your fleet(s). It is therefore advisable that you extend your weapons range as much as possible, and/or enter as close as possible to the Colossus so that you may engage it before it leaves orbit (as you will not get the achievement if the firing process is interrupted by leaving orbit before your attack).||2.0||H|
|Defeat a Fallen Empire Titan fleet with your own Titan.||Not all FE spawn with a Titan. It is recommended to increase number of FE in the galaxy to increase the chance of one of them posessing a Titan. A lone Titan won't move to systems where there are superior enemy fleets.||2.0||VH|
|Has been the first to open a L-Gate||Starting a game with no AI empires make getting this achievement a matter of time||2.1||M|
|Make friends with a Space Amoeba||See Lost Amoeba for event chain details||2.1||M|
|Has defeated the Voidspawn||See the Voidspawn main article for information in how to defeat it.||2.1||H|
|Has defeated the Tiyanki Matriarch||See the Tiyanki Matriarch main article for information in how to defeat it.||2.1||H|
|Has defeated the Scavenger Bot||See the Scavenger Bot main article for information in how to defeat it.||2.1||H|
|Have the Corporate government type and have branch offices on other empires' capitals > 5||The capital of a subject empire counts for this achievement, this could help in case the galaxy is full of unfriendly empires that won't accept a commercial pact by making them your subsidiaries. Note that opening branch offices as Criminal Syndicate does not award this achievement.||2.2||M|
|Has constructed a complete Matter Decompressor||A repaired destroyed Matter Decompressor does not count||2.2||H|
|Has 4 completed Megastructures.||Repaired destroyed Megastructures also count, which can be useful if you lack enough DLC to get 4 normally.||2.2||H|
|Has constructed a complete Mega-Art Installation (including the Perfection stage) in a system within a nebula||A repaired destroyed Mega-Art Installation does not count||2.2||H|
|Has constructed a complete Strategic Coordination Center||A repaired destroyed Strategic Coordination Center does not count||2.2||H|
|Has constructed a complete Interstellar Assembly||A repaired destroyed Interstellar Assembly does not count||2.2||H|
|Win the Galatron in the Reliquary or take it from another empire||The Galatron is a very rare reward from the Caravaneers reliquaries. Each reliquary has a 0.5% chance of containing the Galatron, and only 6 reliquaries can be bought during a game, requiring an average of 34 games to obtain it... or you can make a save file just before you buy a reliquary, and make dozens of copies to load and discard until you find what you're looking for (Documents\Paradox Interactive\Stellaris\save games). This may also be obtained along with "Raiders of the Lost Galatron" by taking the Galatron from an AI empire that has it.
|Capture the Galatron from an empire with it in war||Getting the Galatron gives all empires a CB for taking it from its current owner, because of that there are two ways of going about with this. Either wait and hope an empire gets it from the reliquaries and then declare war on them, or get the Galatron yourself, lose it in a war and reconquer it after the truce.||2.3||I|
|Use the Reverse-Engineer Arcane Technology relic option||Requires the Arcane Deciphering technology which unlocks Reverse-Engineer Arcane Technology option, which for 5 Minor Artifacts can be activated and will give 1 of 4 possible outcomes at random, getting either a random technology or a bonus to tech speed will give the achievement.||2.3||E|
|Has >99 Minor Artifacts||Getting the Rubricator relic may help in cases where no other way to obtain minor artifacts is available.||2.3||E|
|Finish the Zroni Precursor chain||As the archaeological site to start the Zroni chain is only found on habitable planets it may help to only survey those to prevent another precursor chain from being triggered.||2.3||M|
|Finish the Baol Precursor chain||2.3||M|
|Own at least 5 relics||Starting a game with no AI empires and on a Huge galaxy makes getting this achievement a matter of time.||2.3||M|
|Level up a Federation you are in||The Common Ground and Hegemon Origins make this achievement much easier||2.6||VE|
|Have your Diplomatic Weight > 9000||Achievement is easily achieved by the endgame of a typical playthrough.||2.6||E|
|Be the leader of a Level 5 Federation||The Common Ground and Hegemon Origins make this achievement faster to get||2.6||E|
|Reject the creation of the galactic community and have at least once left a Federation||Achievement will only be awarded after the galactic community is created, not when you refuse to join.||2.6||E|
|Defeat an empire that uses the Supremacist Diplomatic Stance with the Humiliate Wargoal||To humiliate another empire, you must have a rivalry against them and no access to Ideology war goals. See Warfare. You may have to send envoys to harm relations first. For this achievement, the other empire must be in Supremacist Diplomatic Stance at the time of war declaration.
Create a new custom empire that is Fanatic Militarist and Authoritarian, has the Nationalistic Zeal and Warrior Culture civics, and which has a founder species with the Conformists, Fleeting, and Traditional traits.
This sets up a game with you vs. the AI empire defined earlier. When the AI completes the Supremacy tradition tree it should immediately switch to the Supremacist Diplomatic Stance. The AI can complete the Supremacy tradition tree early, a mere 7 years in to the game, or it may complete it later such as around 40-50 years in.
When the AI finishes the Supremacy tradition tree it will prefer to switch to or stay in the Supremacist Diplomatic Stance if:
Play normally, find the AI, send envoys to improve relations (to discourage it from declaring war on you) and monitor the AI's diplomatic stance. When it changes to Supremacy build up your fleet to equivalent power and when ready, verify that the AI's diplomatic stance still shows Supremacy and then send envoys to harm relations, rival the AI, and declare a humiliation war. When you win the AI is forced out of the Supremacist Diplomatic Stance and the achievement is obtained.
|Has constructed a complete Mega-Shipyard||A repaired destroyed Mega-Shipyard does not count. Can be gotten without the DLC if a completed Mega-Shipyard is acquired from an Awakened Empire.||2.6||H|
|Build a Juggernaut ship type||2.6||H|
|Pass any Denounce resolution on an Empire that isn't in breach of Galactic Law||Remember that all Major Sanctions must be active first.
Curiously, you don't have to be the denouncer or even be part of the Galactic Community.
|When an operation fails, disavow an Asset instead of trying to re-establish contact.||3.0||VE|
|Destroy 10 ships or conquer a planet of an empire you have not established contact with.||An easy way to get this achievement is to start the game as a Fanatic Purifier (or similar) and engage spaceborne aliens that are already hostile to you.
The achievement will only unlock once the communications are established.
|Become Galactic Custodian, defeat the end-game Crisis, and then end the Custodianship before finishing your term.||This can be done more easily using a mid-game Crisis to become the Custodian. Then approve the Galaxy Defense Force and built an army to be prepared for the end-game Crisis. The term limit is 30 years, but you can increase it with the resolution: Extend Custodianship. After defeating the Crisis, approve the resolution: End Custodianship.||3.0||H|
|Complete 10 different operations (none of the same) during one game||There are only 9 distinct operations by default. More are unlocked by having the End Game Crisis Active (easier) or by using a spy network against the Galactic Emperor (harder). The "Target Seditionists" operation does not count towards this achievement.||3.0||H|
|Pass the Proclaim Galactic imperium resolution with you as Galatic Custodian||To do this, first you must get on the galactic council, then become the custodian, then remove your term limit. Finally, declare the Galactic Imperium. Keep in mind that the AI will be more inclined to grant you greater powers if there is a crisis. (Great Khan and Grey Tempest also have the same effect)||3.0||H|
|Become the Crisis and destroy the Galaxy||You must become the crisis using the ascension perk. You must reach the Existential Threat crisis level by getting 10000 menace. Upon getting this level you start upgrading your Aetherophasic Engine Frame. This costs Dark Matter which you can obtain using your Star-Eaters. You can destroy your own stars. Once upgrading your Aetherophasic Engine to the last stage you activate your engine, destroying the galaxy and giving you the achievement.||3.0||VH|
|With the Galactic Imperium proclaimed, be the instigator of a successful rebellion. You will need to Enforce Demands, not Status Quo, to unlock this achievement.||The hardest part is getting an AI empire to nominate itself the Galactic Custodian and later to proclaim the Galactic Imperium. There are some ways to improve the chances or force an AI empire into this role. Once the AI is Galactic Emperor, you have to bring them down by undermining their authority and sparking a rebellion. You can choose one of these paths:
The waiting game
Increase the council size to 5 (the maximum) and enable veto power. Wait for a crisis to trigger and contain it but don't let it be destroyed. Either veto or quickly pass any resolutions by other council members to free their proposal slots. Ideally, an authoritarian empire nominates itself, as they are more likely to proclaim the Galactic Imperium later. Once a suitable AI empire nominates itself, start building a spy network on them. Support their nomination and any term extensions, but veto the creation of the Galactic Defense Force. Once the Imperium has been proclaimed, assign envoys to undermine imperial influence. When it is low enough, use your spy to start the rebellion. You can also use an operation to lower imperial authority if envoys are not enough. Be ready to fight the Emperor and any loyalists (which can be everyone except you and your vassals). Avoid making claims (and give up exisiting claims), as the "demanding unoccupied system/planet" surrender acceptance malus applies, despite the fact that you cannot conquer systems with this war goal and casus belli.
The multiplayer trick
You can host your singleplayer game in a multiplayer session. When you host/join a multiplayer game, you are given the full list of empires to control. You can pick one that you want to designate as the Imperial Core and push them towards this goal.
After this, you are set to be a part of the Galactic Imperium with the target empire as the Imperial Core.
- The game settings Habitable Worlds and Primitive Civilizations compete with each other during galaxy creation, since Primitives spawn with their own planet.
