Generate space empire names for sci-fi novels, 4X strategy games and tabletop campaigns: imperiums, hegemonies, star dynasties, alien supremacies and rump empires clinging to a dying sun. Each name is built to sound like it already rules a thousand worlds.

About space empire names

A space empire name has to do the work a flag does: announce scale, legitimacy and menace in a few words. Science fiction settled its conventions early: the Galactic Empire, the Imperium of Man and the Klingon Empire all pair a people or a territory with a word for rule. The interesting choices are in the second word. Empire is the default; Imperium sounds Latin, militarized and older; Hegemony implies dominance over nominally free worlds; Dominion, Ascendancy and Supremacy suggest a power still climbing or newly arrived; Dynasty and Throne put the ruling family at the center.

The names here cover the full range. You will find ethnonym empires (Veltharion Star Empire, Kaldari Hegemony), territorial ones (Empire of the Far Spiral, Dominion of the Frozen Arm), dynastic houses (House Vyrenne Dominion, Dynasty of Khaldun), pseudo-Latin imperial titles (Pax Orionis, Imperium Solaris Aeternum), far-future echoes of Earth history (Stellar Khaganate of Altai), alien-phonology states (Qo'Thar Hegemony, Zss'kaal Imperium), machine and hive empires, theocracies, merchant combines, and empires in decline (The Remnant Imperium, The Rump Empire of Corvus).

A Most Serene Empire is old and bureaucratic; a Conquest Empire of Tormund Vale is one warlord's lifetime; an Empire of the Child Emperor is a regency crisis waiting to happen.

How to choose space empire names

  • Decide who named the empire. Citizens say The Imperium or The Radiant Sphere; enemies say the Tyranny of Ashkal; historians add ordinals (Second Terran Empire). Use the insider name in dialogue and the outsider name in propaganda.
  • Match the noun to the government: Empire or Dynasty for hereditary rule, Hegemony for a dominant core world over client states, Ascendancy or Supremacy for an ideological or uplifted-species state, Dominion for a colonial or religious one.
  • For a 4X game like Stellaris, keep the short form to two words so it fits the UI and diplomatic messages, then put the flourish in the full title the player sees once on the empire screen.
  • Seed the name with the empire's origin: a constellation visible from the homeworld (Cygnian Dominion), a founder's house (House Dracovar Imperium), or the thing it worships (Empire of the Sunfather).
  • Borrow a real historical title only when you want the echo: Khaganate, Shogunate, Caliphate and Tsardom all drag their histories with them, which is useful for a far-future successor state and distracting for an alien one.

Frequently asked questions

What is the difference between an empire, an imperium and a hegemony?

In practice they are interchangeable, but in fiction they carry different flavors. Empire is the neutral default. Imperium is the Latin root and reads as militarized and ancient, the Warhammer 40k Imperium of Man being the obvious reference. Hegemony means leadership over states that are technically independent, so it suits a core world that controls client systems through treaties and fleets rather than direct rule.

How do I name a space empire for Stellaris or another 4X game?

Use a short adjective-noun form for the in-game label (Kaldari Hegemony, Ashfall Empire) and save longer titles for the lore. Make sure the name matches your ethics and civics: a Most Holy Empire should be spiritualist, a Machine Empire of Null should be a machine intelligence, a Hesper-Tann Combine Imperium should be megacorp or mercantile.

Should a space empire be named after its species, its capital or its ruler?

All three work, and the choice tells readers something. Species names (Thraxian Dynasty) suggest a monoethnic state; capital names (Empire of Ardanis Prime) suggest a multi-species one held together by a center; ruler or house names (House Vyrenne Dominion) suggest that loyalty runs to a family rather than an idea, which is good setup for a succession war.

Can I use these names in a published book or commercial game?

Yes. The names are original combinations and invented words, free for any use. A few deliberately echo famous fictional empires in structure only; avoid the exact titles of existing franchises (Galactic Empire, Imperium of Man, Romulan Star Empire) if your work is commercial.
