Starbase 12 was a Federation starbase in the Gamma 400 system, in the vicinity of the planets Mab-Bu VI, Pollux IV, Risa and the Ceti Alpha system. In 2167, Admiral Uttan Narsu was the base's commanding officer. (TOS: "Space Seed", TNG: "Power Play")

It has not been said if, like Starbase 11, Starbase 12 was first an Earth Starfleet facility before it became a Federation Starfleet facility.

In 2364 the starbase was evacuated for two days, for which Starfleet Command issued no explanation. Captains Walker Keel, Rixx and Tryla Scott took as further evidence of a conspiracy within Starfleet. (TNG: "Conspiracy")

Starbase 12 also had advanced, secure medical facilities. (TNG: "Aquiel")
