Bilgola Plateau is a suburb in Sydney's Northern Beaches in the state of New South Wales, Australia.

Bilgola Beach on the eastern side features a surf club and kiosk.

Rising to an elevation of 150m above sea level, the suburb has views of the beach and the ocean on the eastern side, and views of the body of water, Pittwater on the western side.

Given its modest elevation, designating it as a plateau is more appropriate, and is now named for the Aboriginal derived name of Bilgola (derived from the local aboriginal language meaning "swirling water"),[5] likely describing Bilgola Beach to the east.

The population of Aboriginal and Torres Strait Islander individuals is low, at 0.3% of the total residents.
