Stellaris has 114 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.

|43||Has invaded Earth, found in the Sol system, while it is in the machine age||Sol has a 50% chance to spawn regardless of galaxy size if no empires has it as its starting system||1.4||H|

|45||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|
|46||Best done by resettling Pops obtained from Migration Treaties or conquests or by conquering The Preserve from an Enigmatic Observers Fallen Empire.

|47||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|
|48||Easiest done by releasing as many 1-planet vassals as needed towards the end of the game||1.4||H|
|49||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.
|50||Destroy the Contingency Secret Lair||Like all crises lowering setting the Crisis Strength setting to to 0.25x makes this a lot easier to achieve.||1.8||VH|
|51||Has captured the Prethoryn queen||Like all crises lowering setting the Crisis Strength setting to to 0.25x makes this a lot easier to achieve.||1.0||VH|
|52||Destroy the last Extradimensional Invader portal||Like all crises lowering setting the Crisis Strength setting to to 0.25x makes this a lot easier to achieve.||1.0||VH|
|53||Has found a way to stop the synthetic infiltration||Complete the event chain to detect synthetic infiltrators during the Contingency crises.||1.0||VH|
|54||Has completed the Horizon Signal event chain and either outcome||Accepting the Worm's offer is the easier choice||1.4||VH|
|55||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|
|56||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|
|57||Has purchased a strategic resource from a trader enclave||1.4||E|
|58||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|
|59||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|
|60||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|
|61||Has peacefully completed the Infinity Machine event and, by luck, resulted in the black hole gaining The Mirror Of Knowledge modifier, among other things||Requires the hidden technosphere_secret country flag to be present which happens in 30% of the cases when a player chooses to help the Infinity Machine.||1.4||H|
|62||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|
|63||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|
|64||Has defeated the Spectral Wraith||See the Spectral Wraith main article for information in how to defeat it.||1.4||H|
|65||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|
|66||Has defeated the Dimensional Horror||See the Dimensional Horror main article for information in how to defeat it.||1.4||VH|
|67||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|
|68||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|
|69||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|

|71||Has unlocked the Transcendence Ascension Perk and entered the shroud||1.5||H|

|73||Requires the Evolutionary Mastery Ascension Perk||1.5||H|
|74||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|
|75||Has constructed a complete Sentry array||A repaired destroyed Sentry Array does not count||1.5||H|
|76||Has unlocked the Synthetic Evolution Ascension Perk, completed the project, and converted all eligible empire citizens to synths||1.5||H|
|77||Has constructed a complete Ring World||A repaired destroyed Ringworld does not count||1.5||H|
|78||Has constructed a complete Science nexus||A repaired destroyed Science Nexus does not count||1.5||H|
|79||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.
|80||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|
|81||Two ascension perks are required to be chosen before the option to unlock machine worlds is made avaiable.||1.8||M|
|82||Have the Rogue Servitor civic and >9 pops which started the game in a Fallen Empire||Refugee pops do not count||1.8||VH|
|83||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.
Stay on Target
Destroy another Empire's Colossus while it is in the process of 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.||2.0||H|
|87||Does not seem to require a Titan in your fleet, only the Fallen/Awakened Empire's.||2.0||VH|
|88||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|
|89||See Lost Amoeba for event chain details||2.1||M|
|90||Has defeated the Voidspawn||See the Voidspawn main article for information in how to defeat it.||2.1||H|
|91||Has defeated the Tiyanki Matriarch||See the Tiyanki Matriarch main article for information in how to defeat it.||2.1||H|
|92||Has defeated the Scavenger Bot||See the Scavenger Bot main article for information in how to defeat it.||2.1||H|
|93||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.||2.2||M|
|94||Has constructed a complete Matter Decompressor||A repaired destroyed Matter Decompressor does not count||2.2||H|
|(74)||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|
|95||Has constructed a complete Mega-Art Installation in a system within nebula||A repaired destroyed Mega-Art Installation does not count||2.2||H|
|96||Has constructed a complete Strategic Coordination Center||A repaired destroyed Strategic Coordination Center does not count||2.2||H|
|97||Has constructed a complete Interstellar Assembly||A repaired destroyed Interstellar Assembly does not count||2.2||H|
|98||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.||2.2||VH|
|99||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|
|100||Complete all levels of an archaeological site (without failing)||2.3||VE|
|101||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|
|102||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|
|103||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|
|105||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|
|106||The Common Ground and Hegemon Origins make this achievement much easier||2.6||VE|
|107||Achievement is easily achieved by the endgame of a typical playthrough.||2.6||E|
|108||The Common Ground and Hegemon Origins make this achievement faster to get||2.6||E|
|109||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. This achievement will also not be awarded if you only leave an origin federation opposed to one you joined/created.||2.6||E|
|110||Overcoming the federational invitation process by vasalizing empires with the subject joining law on yes (requires DLC) is the easiest approach to this achievement.
Possible but difficult to achieve without the DLC, and likely requires player's empire to change their own ethics when already in a federation with five unique ethics from other empires.
|111||Defeat an empire that uses the Supremacist Diplomatic Stance with the Humiliate Wargoal||2.6||H|
|112||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|
|114||Curiously, you don't have to be the denouncer or even part of the Galactic Community.||2.6||H|
- The game settings Habitable Worlds and Primitive Civilizations compete with each other during galaxy creation, since Primitives spawn with their own planet.
