USCGC Sturgeon Bay (WTGB 109) is the newest of the United States Coast Guard 140-foot (43 m) Bay-class cutters.

Homeported in Bayonne, New Jersey, the primary missions of Sturgeon Bay and her crew are Domestic Icebreaking and Ports, Waters, & Coastal Security.

During the winter months, Sturgeon Bay is responsible for providing search and rescue capabilities to the ice-covered areas in New York City and the Hudson Valley, as well as throughout coastal New England.

The cutter also facilitates the safe navigation of commercial product, including gasoline and heating oil, through the ice-choked Hudson River from New York City to Albany.

She was built by Bay City Marine in San Diego, California, launched on 12 September 1987, and commissioned on 20 August 1988.
