Starbase 105 was a Federation starbase administrated by Starfleet.

In an alternate timeline, Starbase 105 was intended to be the destination of the USS Enterprise-D and the salvaged USS Enterprise-C, following that vessel's emergence from a temporal rift in 2366. (TNG: "Yesterday's Enterprise")

This starbase was only mentioned in dialogue.
In the original script, Starbase 105 also alerted the Enterprise-D to the rift, but the line was changed during filming. [1]
According to Star Trek: Star Charts (p. 63) and Stellar Cartography: The Starfleet Reference Library ("Federation Historical Highlights, 2161-2385"), Starbase 105 was located in the Beta Quadrant.
