This is a list of electoral districts or ridings in Canada for the Canadian federal elections of 1925, 1926 and 1930.
Electoral districts are constituencies that elect members of Parliament (MPs) in Canada's House of Commons every election.
The electoral districts and their boundaries for the period of these elections were set based on population, following the sixth decennial census (1921). This was provided under Section 8 of the Constitution Act, 1867, with changes to the districts enacted in the Representation Act of 1924.
