USS Blackfin (SS-322), a Balao-class submarine, was a ship of the United States Navy named for the blackfin, a food fish of the Great Lakes.

Blackfin (SS-322) was launched 12 March 1944 by Electric Boat Co., Groton, Conn., sponsored by Mrs. Phyllis Irwin Lockwood, wife of Rear Admiral Charles A. Lockwood; and commissioned 4 July 1944, Lieutenant Commander George Hays Laird, Jr., in command.

Blackfin arrived at Pearl Harbor 11 September 1944. During her war operations (30 September 1944 – 5 September 1945) she completed five war patrols. Her operating areas included the South China and the Yellow Seas. Blackfin sank the Japanese destroyer Shigure, 24 January 1945, in 06°00′N 103°48′E / 6.000°N 103.800°E / 6.000; 103.800., and a cargo ship for a total of 4325 tons.

The termination of hostilities occurred while Blackfin was on her fifth war patrol. After occupying a lifeguard station and destroying 61 floating mines, she retired to Guam, arriving in Apra Harbor 5 September 1945. After receiving voyage repairs and fuel she proceeded to San Diego where she joined Submarine Squadron 1.
