The IKS Korezima was a Klingon warship in service in the late 23rd century. In the late 2260s, the Korezima was under the command of Commander Kulain.
In 2269, the Korezima was dispatched to the area occupied by the Chatalia generational ship, after the Klingons monitored communications between the USS Enterprise and Starfleet Command concerning the vessel. (TOS novel: World Without End)
