The IKS Rak'hon was a Klingon Imperial Defense Force starship in service in the 23rd century.

As of 2268, the Rak'hon had been stationed in orbit of the planet Sanctuary for several years in search of Klingon criminals when it encountered the USS Enterprise. The ship's captain, Commander Garvak, informed Montgomery Scott he had lost the landing party that landed on the planet. Later, the ship was finally reassigned from its duties and departed Sanctuary.
