Felimida purpurea is a species of colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.
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. The rhinophores and gills are purple-pink with white tips. The body length varies between 35 mm and 50 mm. 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.
