Green Bay is an arm of Lake Michigan, located along the south coast of Michigan's Upper Peninsula and the east coast of Wisconsin. It is separated from the rest of the lake by the Door Peninsula in Wisconsin, the Garden Peninsula in Michigan, and the chain of islands between them, all formed by the Niagara Escarpment. Green Bay is some 120 miles (193 km) long, with a width ranging from about 10 to 20 miles (16 to 32 km); it is 1,626 square miles (4,210 km²) in area.^[2]

At the southern end of the bay is the city of Green Bay, Wisconsin, where the Fox River enters the bay. The Leo Frigo Memorial Bridge (formerly known as the Tower Drive bridge) spans the point where the bay begins and the Fox River ends, as the river flows south to north into the bay. Around mid-bay are Sturgeon Bay and the Peshtigo River. The Sturgeon Bay serves the city named after the bay as a shortcut for large ships to use to bypass the Door Peninsula, while the Peshtigo River serves Peshtigo and Crivitz. Locally, the bay is called the Bay of Green Bay to distinguish it from the city.

The bay is located in parts of five counties in Wisconsin (Brown, Door, Kewaunee, Marinette, Oconto), and two in Michigan (Delta, Menominee).
