The Haro Strait is one of the main channels connecting the Strait of Georgia to the Strait of Juan de Fuca, separating Vancouver Island and the Gulf Islands in British Columbia, Canada from the San Juan Islands of Washington state in the United States.

The strait is a critical part of the international boundary between Canada and the United States. It stretches from the western terminus of the 49th parallel segment of that boundary, and was chosen by the arbitrator in the San Juan Islands dispute (Pig War) over the Rosario Strait.
