Kaleth was a Klingon officer who served in the Klingon Defense Force in the 2370s.

In 2370, Kaleth was visiting Deep Space 9 at the same time as the crew of the IKS K'Tang, and often frequented Quark's on the Promenade where he would regale Quark with stories about the Klingons battle for control of the Antedian sector. (DS9 - Hearts and Minds comic: "Prelude").
