Cogra Bay is a suburb of the Central Coast region of New South Wales, Australia, located on the north bank of the Hawkesbury River 51 kilometres (32 mi) north of Sydney. It is part of the Central Coast Council local government area.
Cogra Bay is bounded by the Hawkesbury River to the south, the mouth of the Mooney Mooney Creek to the west, Mullet Creek to the east, and the Brisbane Water National Park to the north. It consists of a number of properties accessible only by boat or by water taxi from Brooklyn 4 kilometres (2 mi) away, although due to shallow water, some properties have limited access at low tide. Cogra Bay residents have no access to water or power, although many residents use solar power. The Main North railway line skirts the locality, but does not stop within it - the nearest stations being at Brooklyn and Wondabyne.
