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 built by the General Engineering & Dry Dock Company of Alameda, California, and launched on 15 July 1941; sponsored by Mrs. J.

Assigned to the 12th Naval District headquartered at the Mare Island in Vallejo, California, Chinquapin conducted net, salvage, and towing operations out of the Tiburon, California, Net Depot until 31 December 1943 when she sailed for Pearl Harbor, arriving 10 January 1944.

Chinquapin tended nets and laid moorings at Majuro, Kwajalein, and Eniwetok from 15 February 1944 to 27 July, then supported the Marianas occupation by similar operations at Saipan and Guam until 28 October.
