Caloria elegans is a species of colorful sea slug, an aeolid nudibranch, a marine gastropod mollusc in the family Facelinidae.

Facelina quatrefagesi was considered as a synonym of Caloria elegans, but it is morphologically very similar and different valid species.

This marine species occurs in European waters from the British Isles to the Mediterranean Sea; also off the Canary Islands, the Azores and Madeira.
