This is a list of Canada's 343 federal electoral districts (commonly referred to as ridings in Canadian English) as defined by the 2023 Representation Order.

Canadian federal electoral districts are constituencies that elect members of Parliament to the House of Commons of Canada every election. Provincial electoral districts often have names similar to their local federal counterpart but usually have different geographic boundaries. Canadians elected members for each federal electoral district most recently in the 2025 federal election on April 28, 2025.

There are four districts established by the British North America Act 1867 that have existed continuously without changes to their names or being abolished and reconstituted as a riding due to redistricting: Beauce (Quebec), Halifax (Nova Scotia), Shefford (Quebec), and Simcoe North (Ontario). These districts, however, have undergone territorial changes since their inception.
