The Colvos Passage is a tidal strait within Puget Sound in the American state of Washington running west of Vashon Island between the island and the Kitsap Peninsula. It lies just north of the Tacoma Narrows. Colvos Passage has a permanent northbound current, but the rest of Puget Sound either flows southbound or varies with the tide. The communities of Fragaria, Sunrise Beach, Spring Beach, Maplewood, Lisabeula, Cove and Sylvan Beach are located on Colvos Passage.
