Barnston Island is an unincorporated island located in the Greater Vancouver metropolitan area of British Columbia, Canada. Most of it is part of Metro Vancouver Electoral Area A; the remainder is Barnston Island Indian Reserve No. 3, which is outside Electoral Area A limits and under the governance of the Katzie First Nation, headquartered across the river at their main reserve in Pitt Meadows. Although the island is unincorporated and not officially part of any municipality, mailing addresses on the island use Surrey as the city name.
Located in the Fraser River between Surrey and Pitt Meadows, Barnston Island was named in 1827 for Hudson's Bay Company Clerk George Barnston. The island has no direct road access to the rest of the area. It is accessed through the Barnston Island Ferry, a 5-minute ferry passage from Surrey on 104 Avenue across Parson's Channel; the ferry ride is free. Barnston Island's main road travels along the perimeter of the island.
Barnston Island contains mostly farmland and is home to 155 people (2001 census), 46 of whom live on the Barnston Island 3 Indian Reserve, near the southeast part of the island. Statistics Canada defines the island as Vancouver CMA Census Tract 0251.00 of British Columbia.
