Felimida purpurea is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.

[2][3] This species occurs in the Mediterranean Sea, and on the Atlantic coast of Europe and Africa from the Bay of Biscay to Cape Verde[4] and west as far as the Azores.

[5] Felimida purpurea is a chromodorid nudibranch with a plain white to pale purple mantle edged with a line of orange-yellow.

Inside the yellow margin are conspicuous white mantle glands embedded in the tissue.

This species was transferred from the genus Chromodoris to the genus Felimida in a revision of the family Chromodorididae using DNA characters which showed that the Atlantic species of Chromodoris formed a distinct clade.
