Anaheim Bay is an extensive harbor and wetland complex in Orange County, California in the United States. The bay is located on the Pacific Ocean coast of northwestern Orange County next to Seal Beach and is split into several distinct but interconnected parts. The term "Anaheim Bay" generally refers to the deep-water Navy harbor at the bay entrance. Further southeast are the Huntington Harbor, which serves small private vessels, and the Bolsa Bay, a salt-water estuary. Bordering the bay are hundreds of acres of salt marshes, some of the largest remaining such habitats in Southern California.

The Anaheim Bay entrance is located at the westernmost corner of Orange County near the Los Angeles County line. The bay and its associated harbors and wetlands extend southeast along the coast for a distance of some 7 miles (11 km) from Seal Beach towards Huntington Beach; they are protected by a long peninsular barrier beach where Surfside, Sunset Beach and Bolsa Chica State Beach are situated. Los Alamitos Army Airfield and Naval Weapons Station Seal Beach are located adjacent to each other on the north and north-east sides of the bay, respectively.

The bay is divided into an outer and inner deep water harbor. The triangular, 94-acre (38 ha) outer harbor is man-made, protected by two converging rubble breakwaters and maintained to a depth of 43 feet (13 m). The west breakwater has a length of 3,500 feet (1,100 m) and the east breakwater is 3,950 feet (1,200 m). The 96 acres (39 ha) inner harbor is natural but dredged to maintain a minimum depth of 13 feet (4.0 m). The two harbors are connected by a channel 436 feet (133 m) wide and 43 feet (13 m) deep.
