Sci-Fi Country Name Generator

A sci-fi country name has to do two jobs at once: sound like a place people actually live, and hint at how the place came to exist. Most good ones fall into a few families. Coined names with a plausible linguistic root (Tessaly, Orvane, Kaelora, Eskandria) read like nations that have had centuries to settle into their own language. Descriptive English names (Ironhold, Brightmarch, The Lantern Coast) suggest frontier settlers naming what they saw. Latinate and political forms (Aurelian Technocracy, Meridian Free States, Pallas Union) imply a founding document and a government type you can build stories around.

The setting decides which family fits. A near-future Earth works best with recognizable forms bent slightly sideways: Greater Arcadian Republic, Vostok Confederacy, New Lagos Compact. A colonized solar system invites orbital republics, habitat sovereignties and mining commonwealths named for the rock they sit on. A far-future galactic map can go fully coined, with polities, enclaves and hegemonies whose names no longer point to anything on Earth.

This list mixes all of those so you can pick by tone. Pair a coined name with a plain government type (Ilvane Republic) when you want restraint, or let the name stand alone (Velkaar, Ythera, Syrrakis) when the culture should feel old and self-assured.
