USCGC Tahoma (WPG-80) was a United States Coast Guard Cutter built by the Defoe Shipbuilding Company in Bay City, Michigan.

Completed in 1934, the steel-hulled cutter operated on the Great Lakes between 1934 and 1941, attached to the 9th Coast Guard District and homeported at Cleveland, Ohio.

By July 1942, the former cutter had left the Great Lakes to escort Allied convoys in the North Atlantic in the vicinity of Casco Bay, Maine; Ivigtut, Greenland; St. John's and Argentia, Newfoundland; and Sydney, Nova Scotia; into the spring of 1944.

The remainder of her naval service was spent in serving on weather and ice patrol duties between Greenland and Iceland and plane guard operations in the same waters.

Released from duty with the Atlantic Fleet on 30 September 1945, Tahoma was returned to the Coast Guard for a resumption of peacetime service.
