Pakheth was a location about three to four light-years from the Regulus star system.

In 2248, the Federation starship USS King Richard, under the command of Karis Tatenen, was involved in a skirmish with several Klingon scout ships in the vicinity of Pakheth. This encounter was the precursor to the Battle of Vonra. (TOS - Star Trek II Short Stories short story: "The Blaze of Glory")
