Chromodoris willani is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Chromodorididae. The species is named for the renowned nudibranch taxonomist Dr. Richard C. Willan.
Chromodoris willani is similar in appearance to Chromodoris lochi, Chromodoris boucheti and Chromodoris dianae. This species can be distinguished by the very prominent white specks found on the gills and rhinophores.
Individuals in this species can range in color from dark blue to a translucent white. All have black stripes with the center-most stripe typically being non-continuous.
