Talar system was an inhabited planetary system in the Alpha Quadrant. A planet in this system, the Talarian homeworld, was the capital planet of the Talarian Republic.
In 2259, it was listed among several in the region surrounding the Kiley system as being home to a warp-capable civilization. The location of this system was labeled on a stellar cartography chart that was seen on the USS Enterprise's ready room viewscreen. (SNW: "Strange New Worlds")
The system'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. The Talar system was in or near to Talarian space. (PIC: "Maps and Legends", "The Next Generation", "Disengage")
