Barangaroo is an area of central Sydney, New South Wales, Australia. It is located on the north-western edge of the Sydney central business district and the southern end of the Sydney Harbour Bridge. It is part of the local government area of the City of Sydney. The area was used for fishing and hunting by Indigenous Australians prior to colonial settlement. The area is inclusive of The Hungry Mile, the name harbourside workers gave to the docklands area of Darling Harbour East during The Great Depression, where workers would walk from wharf to wharf in search of a job, often failing to find one.

In 2003, the Government of New South Wales determined that the precinct would be redeveloped from shipping and stevedoring facilities to provide more commercial office space and recreational areas. This redevelopment has moved from design contest to concept plan from 2005 to 2012. In the interim, stevedoring facilities have been relocated, some of the site remediated, and temporary alternate uses such as major events implemented, pending major development. The site is managed by an agency of the NSW Government, called the Barangaroo Delivery Authority.

Redevelopment commenced in 2012 and is expected to be entirely completed by 2023. The redevelopment involves parkland with several new apartment buildings, as well as a metro station, hotel, “cultural space” and casino.
