The Division of Warringah is an Australian electoral division in the state of New South Wales.

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.
