Chromodoris elisabethina is a species of very colourful sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Chromodorididae.

It is found in the central area of the Indo-Pacific region from Malaysia, Indonesia, the Philippines and Queensland, Australia to the southern part of Japan.

The branched gills and the rhinophores are orange to yellow and can be withdrawn into pockets under the skin in case of danger.

[6] The mantle edge and the foot are bordered with white and orange to yellow lines in which the width and the colour intensity can vary greatly from a specimen to another.

[7][8][9][10] Chromodoris elisabethina has been demonstrated to be a species complex by a recent molecular phylogeny study.
