The Forest Area (or colloquially "the Forest") is an informal area of suburbs at the most western point of Sydney's Northern Beaches, in the state of New South Wales, in Australia.

The area is located amongst the bushland of Ku-ring-gai Chase National Park and Garigal National Park, east of Middle Harbour and borders Sydney's Lower North Shore.

The Forest District is served mostly by CDC NSW, as part of the Region 14 Contract.

Keolis Downer Northern Beaches run some services.
