Warringah Council was a local government area in the northern beaches region of Sydney, in the state of New South Wales, Australia. It was proclaimed on 7 March 1906 as the Warringah Shire Council, and became "Warringah Council" in 1993. In 1992, Pittwater Council was formed when the former A Riding of Warringah Shire voted to secede. From this point on until amalgamation, Warringah Council administered 152 square kilometres (59 sq mi) of land, including nine beaches and 14 kilometres (9 mi) of coastline. Prior to its abolition it contained 6,000 hectares of natural bushland and open space, with Narrabeen Lagoon marking Warringah's northern boundary and Manly Lagoon marking the southern boundary.

The Northern Beaches is a region within Northern Sydney, in the state of New South Wales, Australia, near the Pacific coast. This area extends south to the entrance of Port Jackson, west to Middle Harbour and north to the entrance of Broken Bay. The area was formerly inhabited by the Garigal or Caregal people in a region known as Guringai country.
