Parramatta, city within the Sydney metropolitan area, eastern New South Wales, Australia. It lies along the 15-mile- (24-km-) long Parramatta River (which enters Port Jackson harbor).
The second European settlement in Australia, it was founded in 1788 by Gov. Arthur Phillip as a western outlying farm colony of Sydney. Initially called Rose Hill, it was renamed Parramatta, an Aboriginal word meaning “head of waters,” in 1791, the year after it was proclaimed a town. In its early years it was larger and of greater importance than Sydney. Incorporated as a municipality in 1861, it became a city in 1938 and was subsequently expanded several times by the inclusion of surrounding centers. It serves a region with plant nurseries and mixed vegetable farms and is industrialized to include motor-vehicle assembly, flour milling, and textile, paint, tile, tire, and asbestos manufacture.
Parramatta has many historic buildings, including the Elizabeth Farm homestead (1793), the country’s oldest home still standing; Experiment Farm Cottage (1798), the farm founded to demonstrate the possibility of self-sufficiency for settlers; the Old Government House (1799), Australia’s oldest public building and part of a UNESCO World Heritage site designated in 2010; and the Kings School (1832). Pop. (2006) local government area, 148,323; (2011) local government area, 166,858; (2023 est.) city, 269,145.
