Plebidonax deltoides or Donax deltoides is a small, edible saltwater clam or marine bivalve mollusc, endemic to Australia. It belongs to the family of either the Donacidae, or the related Psammobiidae. It is most widely known as the pipi (also spelled pippi, plural pipis or pippies) in the eastern states of its native Australia. In South Australia, it is called the Coorong cockle, Goolwa cockle, or Goolwa pipi, for the region where it is most abundant, or by its Ngarrindjeri name, kuti. In south-eastern Queensland, it is often also known as eugarie or (y)ugari, a borrowing from the local Yugambeh and Ugarapul languages.
This species should not be confused with the bivalve Paphies australis (of the family Mesodesmatidae), endemic to New Zealand and also called "pipi".
