Tomaree is a national park in New South Wales, Australia, 145–155 km (90–96 mi) northeast of Sydney in the Port Stephens local government area. It is located on the shores of the Tasman Sea, extending north from Fishermans Bay to Shoal Bay passing through Boat Harbour, One Mile, Nelson Bay and Fingal Bay.
Most entry points to the park are indicated by signs installed by the New South Wales National Parks and Wildlife Service which usually indicate any activities that may be prohibited within park boundaries.
Two prominent locations in the park are Point Stephens Light, a lighthouse built in 1862 and the World War II gun emplacements on Tomaree Head which were built in 1941, the location of the No. 20 Radar Station RAAF.
