Anna Bay is the name of a suburb, a town and a bay in the Port Stephens local government area in the Hunter Region of New South Wales, Australia. The suburb and town are immediately adjacent to the north-eastern end of Stockton Beach and the town provides one of the major entry points to the beach here. Both were named after the bay of the same name which is now located in the adjacent suburb of One Mile.
During World War II Stockton Beach was heavily fortified against a possible amphibious assault by Imperial Japanese forces and a line of tank traps was installed to prevent entry to the local area through the town. Many of the tank traps were removed after the war and now feature significantly around the car parking areas at the beach.
