USS Gudgeon (SS-211) was the first American submarine to sink an enemy warship in World War II. She was the last of the long-range Tambor-class vessels commissioned for the United States Navy in the years before the country entered World War II. Gudgeon scored 14 confirmed kills, placing her 15th on the honor roll of American submarines. She was declared overdue, presumed lost with all hands, on 7 June 1944. Of the twelve Tambor-class submarines, only five survived the war.

USS Gudgeon (SS/AGSS/SSAG-567), a Tang-class submarine, was the second ship of the United States Navy to be named for the gudgeon, a species of small fresh-water minnow.
