USS Chinquapin (YN-12/AN-17) was an Aloe-class net laying ship built for the United States Navy during World War II. Originally ordered as USS Fir (YN-2), she was renamed and renumbered to Chinquapin (YN-12) in October 1940 before construction began. She was launched in July 1941, and completed in October 1941. Placed in service at that time without being commissioned, she was commissioned in January 1943, and decommissioned in March 1946. She was placed in reserve at that time and scrapped in 1976.
