Britannia Beach is a small unincorporated community in the Squamish-Lillooet Regional District located approximately 30 kilometers north of Vancouver, British Columbia on the Sea-to-Sky Highway on Howe Sound. It has a population of about 300.
The community first developed between 1900 and 1904 as the residential area for the staff of the Britannia Mining and Smelting Company. The residential areas and the mining operation were physicaly interelated, resulting in coincidental mining and community disasters through its history.
Today, the town is host to the British Columbia Museum of Mining, on the grounds of the old Britannia Mines. The mine's old concentrator facilities, used to separate copper ore from its containing rock, is a National Historic Site of Canada.
