Alexander Peter Cockburn (April 7, 1837 – June 2, 1905) was a Canadian businessman and political figure.

After a visit to the Muskoka District in 1865, he moved to Gravenhurst, where he opened a general store, established stagecoach service and initiated steamboat service on Lake Muskoka.

While in office, he lobbied for improved rail and water links to the region.

Cockburn also published pamphlets describing the natural beauty of the region, aimed at promoting tourism.

His steamboat operation expanded to ten ships and a booming resort industry developed in the Muskoka region, that has continued to the present time.
