Longueville is a suburb on the Lower North Shore of Sydney, in the state of New South Wales, Australia 8 kilometres north-west of the Sydney central business district, in the local government area of the Municipality of Lane Cove.
Longueville is a small residential suburb on the peninsula between Tambourine Bay and Woodford Bay, on the banks of the Lane Cove River. Originally a home to manufacturing industries, the suburb had its beginnings as a residential area in the 1870s. Longueville was officially proclaimed a suburb in the 1920s.
Before settlement, Longueville was the home of the Cam-mer-ray-gal people of the Ku-ring-gai Aboriginal Tribe. Today the suburb is home to some of Australia's most expensive real estate, with the Sydney Morning Herald ranking it as Sydney's fourth most-expensive suburb.
