Xelatians are a species of aquatic humanoid cephalopods native to Xelata, the third planet of the Tau 56 system.

The Federation made first contact with this race in 2282. The Xelatians were in the process of obtaining membership into the United Federation of Planets as of 2286 and had a delegation present during the "Whalesong Crisis" on Earth (FASA RPG: Star Trek IV: The Voyage Home Sourcebook Update).
