USS Snook (SS-279), a Gato-class submarine, was the first ship of the United States Navy to be named for the common snook, an Atlantic marine fish that is bluish-gray above and silvery below a black lateral line.

The common snook is a species of marine fish in the family Centropomidae of the order Perciformes. The common snook is also known as the sergeant fish or robalo. It was originally assigned to the sciaenid genus Sciaena; Sciaena undecimradiatus and Centropomus undecimradiatus are obsolete synonyms for the species.
