Rosny Park is a suburb of Hobart, Tasmania, located in the City of Clarence on the eastern shore of the Derwent River.

The Rosny Barn was re-developed in 2006 to a multi-purpose, small capacity arts venue situated in the cultural hub of Hobart's Eastern Shore.

Rosny Cottage (now a Museum) and the School House Gallery (a replica of a schoolhouse that was built at Osterly in central Tasmania in 1890) are also located within the walls of the farm.

Rosny Park is home to Bellerive Police station, the Tasmanian Fire Service, and Bayfield Street Medical Centre, as well as Warrane barracks of the 12th/40th battalion of the Australian Army Reserve.

Nearby Charles Hand Memorial Park provides public green space and also hosts an annual Christmas Carols by Candlelight ceremony which draws crowds in the thousands.
