USS Suncook (YN-99/AN-80) was a Cohoes-class net laying ship which was assigned to protect United States Navy ships and harbors during World War II with her anti-submarine nets. Her World War II career was short lived; however, after decommissioning, she was reactivated in 1962 for use as a research ship for the U.S. Bureau of Mines, where she served as Grass Valley.
