Kendarayans were a humanoid race native to the planet Kendaray in the Gamma Quadrant. Kendarayans are notable for their symbiotic relationship with the Barth, colonies of microscopic organisms that cover the Kendarayans with a protective barrier, shielding them for pathogens and allowing them to live as long as 300 years.

A small number of Kendarayans, known as Dream Riders, are able to bring themselves to a near-death state, and to move back and forth between the barrier of life and death.

In 2372, the Kendarayans sent an envoy named Sellassars to meet with representatives of the Federation, in order to share intelligence about the Dominion. (TNG eBook: Slings and Arrows: That Sleep of Death)
