K'Leht was a male Klingon and the commander of the IKS Khitomer's Revenge in the 2360s.

In 2369, K'Leht's sister and her husband were killed by Mard and he assigned to bring him to Qo'noS for trial. K'Leht planned to seek medical attention for Mard on Deep Space 9 and let him escape, hoping the space station crew would kill his prisoner. Kira Nerys gained access to Klingon records and learned the truth and Benjamin Sisko threatened to tell the Klingon High Command everything he knew if Mard did not get to Qo'noS safely.
