Gympie ( /ˈɡɪmpi/) is a regional town in the Wide Bay-Burnett region of Queensland, Australia. It is about 160 kilometres (100 mi) north of the state capital, Brisbane. The city lies on the Mary River which has periodically caused flooding in the town. Gympie is the administrative centre for the Gympie Region area. At the 2006 census, Gympie had a population of 10,933.

Gympie is famous for its gold field. It contains a number of historic buildings registered on the Queensland Heritage Register.

Gympie's name derives from the Kabi (the language of a tribe of Indigenous Australians that historically lived in the region) word "gimpi-gimpi" (which means "stinging tree"), which referred to Dendrocnide moroides. The tree has large, round leaves that have similar properties to stinging nettles. The town was previously named "Nashville", after James Nash, who discovered gold in the area in 1867. The name was later changed to Gympie in 1868.

Originally settled for grazing purposes, the area became prominent when James Nash reported the discovery of 'payable' alluvial gold on 16 October 1867. At the time Queensland was suffering from a severe economic depression and the discovery probably saved the colony from bankruptcy. A memorial fountain was built in Gympie's Park in honour of Nash's discovery. This event is still celebrated today during the Gympie Gold Rush Festival, with 10 days of cultural events held in October.Gold mining still plays a role in the area's fortunes, along with agriculture (dairy predominantly), timber and tourism.
