Capellinia doriae is a species of sea slug or nudibranch, a marine gastropod mollusc in the family Eubranchidae.

[2] This species was described from Genova, Italy.

[1] It has also been reported in error from the Atlantic coast of France and the coasts of Great Britain and Ireland but these records refer to a closely related species, Capellinia fustifera.
