Collaroy Plateau is a suburb of northern Sydney, in the state of New South Wales, Australia. Collaroy Plateau is 22 kilometres north-east of the Sydney central business district, in the local government area of Northern Beaches Council and is part of the Northern Beaches region.

Collaroy Plateau was designated as a separate suburb in 1977 with a postcode of 2098, but was reassigned as a locality within Collaroy in 1984, with the postcode changing to 2097 as part of Collaroy. In 2001 all localities were renamed Urban Places. In 2011 Collaroy Plateau, along with Wheeler Heights, was re-established as a suburb by the Geographical Names Board of NSW, after lobbying by the community, who had never ceased considering it to be a suburb since its loss of that title in 1984.

Collaroy Plateau has some of the most spectacular views on the Northern Beaches. Various parts of Collaroy Plateau overlook Collaroy Beach, Long Reef Beach, Narrabeen Beach and Narrabeen Lagoon.

Collaroy Beach is also the landing point of the PPC-1 submarine cable, one of three backhaul communication links connecting Australia to the wider Internet.

The name Collaroy is aboriginal for "big reeds", and the suburb began its life as part of Narrabeen. In 1881, the steamer "Collaroy" ran aground on Long Reef at the southern point of the suburb. Crowds came from all around the district to see the wreck that subsequently gave its name to the suburb. Its anchor can still be found at the Narrabeen Primary School.

Collaroy Plateau Post Office opened on 1 April 1949 and closed in 1988. Collaroy Plateau West Post Office opened on 1 November 1967 and was renamed Collaroy Plateau in 1996.

Collaroy Reservoir (Elevated) (WS 30) is one of a small group of reservoirs in the Sydney Water system, which was originally constructed for railway purposes. It demonstrates a significant adaptation of railway technology for water supply purposes. The listing includes the reservoir and all associated pipework, valves and valve houses to the property boundary.
