Great Egg Harbor Bay (or Great Egg Harbor) is a bay between Atlantic and Cape May counties along the southern New Jersey coast. The bay has a total area of 8.5 sq mi (22 km2). Its depth ranges from shallow waters in the southern extension, called Peck Bay, to a 33 ft (10 m) deep channel.

The Great Egg Harbor River and its 17 tributaries empty into the bay.

During the Sangamonian interglacial period, the Great Egg Harbor River existed as a delta that covered much of southern Cape May County. Over time, the waterway shifted its course, emptying into the Atlantic Ocean at the Great Egg Harbor Inlet between Ocean City and Longport. In the eastern periphery, the bay measures 5.0 mi (8 km) along the coast, bordered by Ocean City on the east.
