The Sudbury District is a district in Northeastern Ontario in the Canadian province of Ontario. It was created in 1907 from parts of Algoma District.

Although the Sudbury District takes its name from the city of Greater Sudbury, Ontario, and geographically encloses the city on all sides, the city is not politically part of the district. The city instead has comprised its own separate geographic division since 1973, when the Regional Municipality of Sudbury was created. The Regional Municipality of Sudbury was separated from the district so that its needs could not dominate the much smaller communities in the district.

In 2001, the population of the Sudbury District was 22,894.

Provincial Highways

The Sudbury District is served by Trans-Canada Highways 17, which leads from the community of Walford (Sables-Spanish Rivers) in the west to the community of Warren (Markstay-Warren) in the east, and 69, which enters the district at French River and exits at the southern boundary of Greater Sudbury.

The Ontario government is converting Highway 69 to a freeway. Construction, and renumbering as Highway 400, are expected to be complete by 2013.

Other primary provincial highways in the district are:

• Highway 6, which extends from Highway 17 south to Whitefish Falls, where it enters the Manitoulin District,
• Highway 64 , which runs from Highway 69 east and north through the Municipality of French River, and enters the Nipissing District at Mashkinonje Provincial Park ,
• Highway 101, which extends from the boundary of Algoma District, west of Chapleau, to the boundary of Timiskaming District, just outside of Timmins, Ontario,
• Highway 129 , which runs from Highway 101 to the boundary of Algoma District south of Chapleau ,
• Highway 144 , which runs from the northwestern city limits of Greater Sudbury north to the boundary of Timiskaming District, just outside of Timmins.

The Sudbury District also has a number of secondary provincial highways, which are the analogue in a district to county or municipal roads in Southern Ontario. They are important connections to the communities they serve, but are not significant routes for through traffic. The secondary highways are:

• Highway 528, connecting the community of Wolseley Bay (French River) to Highway 64,
• Highway 528A, which provides access to the south side of the water body at Wolseley Bay,
