Dall's porpoise (Phocoenoides dalli) is a species of porpoise endemic to the North Pacific. It is the largest of porpoises and the only member of the genus Phocoenoides. The species is named after American naturalist W. H. Dall.

Dall’s porpoise is the only member of the genus Phocoenoides. The dalli- and truei-types were initially described as separate species in 1911, but later studies determined that the available evidence only supported the existence of one species. Currently, these two color morphs are recognized as distinct subspecies, Dall's porpoise (Phocoenoides dalli dalli) and True's porpoise (Phocoenoides dalli truei).

The Dall’s Porpoise (P. dalli dalli) images in this gallery are from the Straight of Juan de Fuca, Washington State and the True Porpoises (P. dalli truei) are from the Kuril Islands Russia.
