Porcellanopagurus edwardsi is a species of hermit crab that lives in the waters around New Zealand and its subantarctic islands.

The closely related species P. filholi has a more northerly distribution, overlapping with that of P. edwardsi only in the region of the Banks Peninsula.

[2] Unlike most hermit crabs, Porcellanopagurus edwardsi is almost symmetrical, but its abdomen is bent back over the carapace, so that the pleopods are dorsally situated.

The abdomen is "grossly distorted",[3] and is usually covered by the shell of a bivalve or limpet, in contrast to the gastropod shell used by most hermit crabs.

[1] The cephalothorax is flattened and extends outwards in a number of lobes, the largest of which is the rostrum at the front of the animal.
