Starbase 39-Sierra, or, more simply, Starbase 39, was a Federation starbase. This base was located in the Beta Quadrant.

In 2259, the location of this starbase was labeled on a stellar cartography chart that was seen on the USS Enterprise's ready room viewscreen. (SNW: "Strange New Worlds", "Spock Amok")

In 2364, the helmsman of the USS Enterprise-D, Geordi La Forge, suggested the USS Enterprise-D could deliver their late-20th century passengers at this starbase. It was five days away, at warp 8, from the position of the Enterprise-D at the edge of the Romulan Neutral Zone in Sector 30. According to La Forge, it would reduce their travel time back to Earth by months. Additionally, Captain Picard thought the extra time would allow them to better acclimate to the 24th century. (TNG: "The Neutral Zone")

From 2375 to 2379, Raffaela Musiker was assigned to this starbase as a security officer. (PIC: "The Next Generation")

The starbase's location was labeled in a Federation star chart that was in Fleet Admiral Kirsten Clancy's office at Starfleet Headquarters in 2399 and on the bridge of the USS Titan-A in 2401. Starbase 39-Sierra was in or near to space claimed by the Romulan Free State. (PIC: "Maps and Legends", "The Next Generation", "Disengage")

In 2401, the location of Starbase 39-Sierra was labeled on a star chart that was seen on the USS Stargazer's bridge viewscreen. The chart was used to show the location of the combined Starfleet-Borg armada and where it needed to go to face a galactic-level threat. (PIC: "Farewell")

Later that year, this starbase's position was labeled on a star chart used by Captain William T. Riker during his attempt at finding the last known location of the SS Eleos XII. (PIC: "The Next Generation")
