The House of Korath was a powerful house in the Klingon Empire in the early 25th century.

In an alternate timeline in 2404, Admiral Kathryn Janeway and Ensign Miral Paris negotiated with Korath of the House of Korath so Janeway could obtain a chrono deflector from them to travel back in time to the year 2378. (VOY: "Endgame")
