Phyllidiopsis loricata is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod mollusk in the family Phyllidiidae.

It has been reported from the Great Barrier Reef, Timor Sea (northern Australia), Guam, the Marshall Islands and Enewetok Atoll.

[3] Specimens from Réunion in the Indian Ocean may be a different species.

It is a moderately large Phyllidiid, growing to about 40 mm in length.

It is similar to Phyllidia scottjohnsoni but that species has black spots along the midline of the back.
