Klingon-Romulan border
The Klingon-Romulan border was the border between the Klingon Empire and the Romulan Star Empire in the Beta Quadrant.

Camp Khitomer was located near the border on the Klingon side. ()

In early 2368, Jean-Luc Picard placed a fleet of twenty-three Federation starships, designed to establish a tachyon detection grid along the Klingon-Romulan border in an attempt "to prevent any external power from interfering in Klingon affairs." According to Commander Sela, "deploying an invasion fleet along our border is a clear act of aggression. [..] It will not be tolerated." She then gave Picard "twenty hours to recall your ships and return peacefully to Federation territory." () 

In early 2372, the Klingon Empire attacked several Romulan outposts along the border, in an attempt to "[reassert] themselves all over the quadrant." ()
