North Curl Curl is a suburb in northern Sydney, in the state of New South Wales, Australia 19 kilometres north-east of the Sydney central business district, in the local government area of Northern Beaches Council.

The names were changed as a part of a renaming program in the 1980s to reflect the true location of the lagoons.

Wingala is an 'urban place' as classified by the Geographical Names Board in the north and western parts of the suburb, lying on the southern slopes of a hill that overlaps into Dee Why.

Headland Road marks the northern boundary, while the Tasman Sea lies to the east.

The suburb is generally characterised by the sometimes steep southern slopes of Wingala Hill and Dee Why Head to the north, which flatten out into the former floodplain of the lagoon towards the south.
