Porpoise Bay (66°30′S 128°30′E) is an ice-filled embayment about 90 miles wide indenting the coast of Antarctica between Cape Goodenough and Cape Morse. The United States Exploring Expedition (1838-42) under Charles Wilkes applied the name "Porpoise Bay", after the USEE brig "Porpoise", to a large bay at about 66°S, 130°E. US-ACAN's identification of Porpoise Bay is based on the correlation of Wilkes' chart (1840) with G.D. Blodgett's reconnaissance map (1955) compiled from air photos taken by USN Operation Highjump (1946-47). The name has been applied to the large embayment lying close southwest in keeping with Wilkes' original naming.

Porpoise Basin (66°10′S 128°30′E) is an undersea basin, located close to Porpoise Bay. Porpoise Canyon (64°20′S 131°0′E) is an undersea canyon located about 300 miles from Porpoise Bay; it is one of the largest canyons in the Wilkes Land Continental Margin.
