Northumberland—Clarke (formerly Northumberland—Peterborough South) is a federal electoral district in Ontario.
Northumberland—Peterborough South was created by the 2012 federal electoral boundaries redistribution and was legally defined in the 2013 representation order. It came into effect upon the call of the 2025 Canadian federal election, held on 19 October 2015. 77% of the riding was formed from Northumberland—Quinte West, 13% from Durham and 10% from Peterborough. The riding was originally intended to be named Northumberland—Pine Ridge.
Under the 2022 Canadian federal electoral redistribution the riding lost its territory in Peterborough County, the townships of Asphodel-Norwood and Otonabee-South Monaghan, to the Peterborough riding. As such, it was renamed Northumberland—Clarke at the 2025 federal election.
Geography The riding is located in Central Ontario along Lake Ontario. It contains the entirety of Northumberland County and the eastern half of the municipality of Clarington.
