Denebia was an unaligned Class M planet proximate to both the Federation and the Klingon Empire in 2270. It was the homeworld to a humanoid race known as Denebians.
This world is known as DenIbya' to speakers of Klingonese.[citation needed]
The Klingon Krong was exiled to Denebia following his dishonorable killing of his commanding officer, M'kar.
Leonard McCoy and Montgomery Scott spent a day in the city of Meekrab on Denebia in 2270, after being dropped off by the USS Lexington to await the arrival of the USS Enterprise. (TOS - Constellations short story: "Where Everybody Knows Your Name")
- Denebia is distinct from Deneb V, and is not a part of the Deneb system. It is also described as the place where Denebian slime devils come from, though that may be in reference to the drink rather than the animal.
