The Strait of Georgia (French: Détroit de Géorgie) or the Georgia Strait[3] is an arm of the Salish Sea between Vancouver Island and the extreme southwestern mainland coast of British Columbia, Canada, and the extreme northwestern mainland coast of Washington, United States. It is approximately 240 kilometres (150 mi) long and varies in width from 20 to 58 kilometres (12 to 36 mi).[4] Along with the Strait of Juan de Fuca and Puget Sound, it is a constituent part of the Salish Sea.

Archipelagos and narrow channels mark each end of the Strait of Georgia, the Gulf Islands and San Juan Islands in the south, and the Discovery Islands in the north. The main channels to the south are Boundary Pass, Haro Strait and Rosario Strait, which connect the Strait of Georgia to the Strait of Juan de Fuca. In the north, Discovery Passage is the main channel connecting the Strait of Georgia to Johnstone Strait. The strait is a major navigation channel on the west coast of North America, owing to the presence of the port of Vancouver, and also due to its role as the southern entrance to the Intracoastal route known as the Inside Passage.
