Okenia felis is a species of very small sea slug, specifically a dorid nudibranch, a marine gastropod mollusc in the family Goniodorididae.

[2] This species was first discovered in 2008 at Point Lobos State Reserve, in Monterey County, California, by local divers.

This species has so far been observed only in Carmel-by-the-Sea, California at 37–45 m depth.

The rhinophores are distinctive in that the ends are void of lamellae.

Reaching only about 7–8 mm in length, this deeper water species feeds on brown ctenostomatous bryozoans.
