Minister responsible for Constitutional Affairs

The Minister responsible for Constitutional Affairs was the Canadian cabinet minister responsible for constitutional affairs during the preparation for the attempted Charlottetown Accord constitutional amendments. The position was created on April 21, 1991 following the failure of the Meech Lake Accord and was abolished June 24, 1993 following the failure of the Charlottetown Accord.

Joe Clark was the only person to hold this post.

The position was sometimes informally called "unity minister" in sources such as media accounts. This same informal appellation was given to the subsequent position Minister of Intergovernmental Affairs.
