USS Monomoy (AG-40) was a commercial cargo ship acquired by the U.S. Navy during World War II. She was outfitted with guns and depth charges and sent into the dangerous waters of the North Atlantic Ocean to furnish data used to predict storm movement and severe weather conditions to safeguard the continuous movement of merchant convoys, naval warships, and airplanes between North America and the United Kingdom, Murmansk, and other destinations. She served as an escort vessel when required. She was crewed by the U.S. Coast Guard and was eventually transferred to that agency as USCGC Monomoy (WAG-275).
