In Canadian politics, a Quebec lieutenant () is a Quebec politician who is selected by the leader of a federal party to be the main advisor or spokesperson on issues specific to Quebec. This is particularly the case when the leader is an anglophone, though several francophone leaders have also had Quebec lieutenants. It is typically filled by a Member of Parliament or at least a current or former candidate for Parliament. The position is usually a well-known but often unofficial assignment, and has no official legal status.
