Federation Name Generator

A federation name has to say two things at once: that many members joined voluntarily, and what holds them together. The classic sci-fi form, United Federation of Planets, does both with a plural noun and a unifying adjective, and most good federation names follow that logic. The joiner word can be Federation, Federated, Confederation, Commonwealth, Union or Compact; the members can be worlds, systems, colonies, stations, cantons or cities; and the anchor is usually a place, a star, a founding treaty or a shared trait such as free, allied or sovereign.

Real stars and constellations make convincing anchors because they already sound like places: Tau Ceti Federation, Arcturan Federation, Federation of the Pollux Reach. Invented anchors work when they look like real place names, as in Federated Worlds of Kessar. Historical federations add other patterns worth stealing: the Swiss cantons, the Hanseatic towns and the Iroquois confederacy all named themselves after the members or the land rather than an ideology, which is why Federation of the River Cantons or Federation of the Five Harbours feels older and more grounded than anything with Galactic in it.

This generator covers all of those registers, from polished interstellar unions to rough frontier compacts and planetside federations of towns and clans, so you can match the name to the tone of the setting.
