The Quundar was a Klingon Bird-of-Prey in service in the 23rd century.

In 2264, the Klingon rebel Koronin, won the ship off its captain, and renamed it Quundar. Koronin then took the Quundar on a mission into the Federation Phalanx to attack the USS Enterprise. However, the attack was halted when they discovered that the Enterprise had encountered an alien generation ship. A peace agreement was made and the Quundar's crew were entertained by Amelinda Lukarian and her Warp-Speed Classic Vaudeville Company. (TOS novel: Enterprise: The First Adventure)
