Kelva was an inhabited planet in the Andromeda Galaxy. This was the homeworld for the Kelvans, a warp-capable non-humanoid species. In the mid-20th century, Kelva was the capital planet of the Kelvan Empire.
According to an idea suggested by Spock, a robot ship could be sent to Kelva along with the Federation proposal of peaceful relations and to suggest some planets in the galaxy that the Kelvans could colonize. The Kelvan response would, however, take six hundred years to arrive.
