Starbase 2
Starbase 2 was a Federation starbase administered by Starfleet. It had a well-equipped and -staffed medical facility. Located in the Alpha Quadrant, it was located seventy-two hours away from Camus II at warp 2.

In 2248, Andrea Lopez was born here. ()

In 2259, the location of this starbase was labeled on a stellar cartography chart that was seen on the 's ready room viewscreen. () 

In 2269, Commander Spock suggested taking Doctor Janice Lester (with James T. Kirk in her body, a fact unknown to anyone but the two of them at the time) to Starbase 2 instead of Benecia Colony, whose facilities were inferior. Given the nature of Lester's condition, "Kirk" (Lester in his body) was inclined to disagree, saying that "Lester" would die before they arrived. Spock suggested they travel at maximum speed, but "Kirk" dismissed his suggestions out of hand (wanting Kirk to die). ()
