Murphydoris is a genus of sea slugs, specifically dorid nudibranchs, marine gastropod molluscs in the family Goniodorididae.

[1] The generic name Murphydoris was created to honor the zoologist and ecologist D. H. Murphy, who is on the staff at the National University of Singapore.

[1] The genus Murphydoris lacks peri-anal ctenidia (comb-like respiratory gills); its rhinophores are non-lamellate and its radula formula is n x 1.1.0.1.1.

[1] The type locality for Murphydoris singaporensis is mangroves between Kranji and Sungei Buloh Wetland Reserve in Singapore.

It was found along the coast of Singapore, between colonies of the bryozoan Sundanella sibogae (order Ctenostomatida).
