'Revillagigedo Channel' is an ocean channel in the Alexander Archipelago of the U.S. state of Alaska. Extending 56 km (35 mi) northwest from the Dixon Entrance, it lies between the mainland to the east, Revillagigedo Island to the north, and Duke Island and Annette Island to the southwest. It is part of the Inside Passage to Ketchikan.
The channel was named for Juan Vicente de Güemes Padilla Horcasitas y Aguayo, 2nd Count of Revillagigedo, viceroy of New Spain, in 1793.
