Parry Sound District is a census division of the Canadian province of Ontario. Its boundaries are District of Muskoka to the south, the Sudbury District to the north-northwest, the French River and Lake Nipissing in the north, Nipissing District and North Bay in the north and east and parts of Algonquin Park in the northeast.
In 2016, the population was 42,824. The land area is 9,322.80 square kilometres; the population density was 4.5 per square kilometre.
It is geographically in Southern Ontario, but the Ontario and federal governments admister it as part of Northern Ontario. Like other census divisions in Northern Ontario, it does not have an incorporated county, regional municipality, or district municipality level of government but instead serves as a purely territorial division like the other districts of Northern Ontario. Instead of an upper tier of municipal administration, all government services in the district are provided either by the local municipalities or by the provincial government itself. Some communities which are not part of any incorporated municipality are served by local services boards.
