Aldisa andersoni is a species of sea slug, a dorid nudibranch, a marine gastropod mollusk in the family Cadlinidae.
This species was described from Pigeon Island, Trincomalee, Sri Lanka. It has subsequently been reported from the Muttom coast, India, and Mirissa, Southern Province, Sri Lanka.
Aldisa andersoni has been found to contain Phorbazole metabolites which are probably derived from its food, a sponge in the family Hymedesmiidae.
