List of Prime Ministers of Canada by religious affiliation

This is a list of Prime Ministers of Canada by religious affiliation. It notes party affiliation after the name.

In early Canadian history religion played an important role in politics. The Conservative Party of Canada was composed mainly of Anglicans and conservative French Canadian Catholics while the Liberal Party of Canada was backed by reform minded French Canadian Catholics and non-Anglican English Canadians. In more recent years religion has played a background role in Canadian politics. Modern Prime Ministers have been reticent about discussing their faith.
