Tsawwassen (; from North Straits Salish: or , meaning "facing the ocean") is a suburban, mostly residential community located on a peninsula in the southwestern corner of the Municipality of Delta, British Columbia, Canada. Tsawwassen provides the only road access to the community of Point Roberts, Washington via 56th Street. It is also the location of BC Ferries' Tsawwassen Ferry Terminal, built in 1959 to provide foot-passenger and motor vehicle access from the Lower Mainland to the southern part of Vancouver Island and the Southern Gulf Islands. Because Tsawwassen touches a shallow bank, the ferry terminal is built at the southwestern end of a 3 km-long causeway that juts out into the Strait of Georgia. The ferry dock and causeway are part of Highway 17.Boundary Bay Airport, a major training hub for local and international pilots, in addition to providing local airplane and helicopter service, is located ten minutes away. The Roberts Bank Superport is also located near Tsawwassen.
To the northwest of the community of Tsawwassen are the lands of Tsawwassen First Nation ("TFN"); a people of Coast Salish ancestry. This land is bounded by the Strait of Georgia on the west, the 2600 block to the north, the 4800 block to the east, and the 1200 block to the south. While also part of TFN lands, the 92-lot residential subdivision of Stahaken was leased for use by the (then) Tsawwassen Indian Reserve to Staheken Developments Ltd., in 1989 for a 99 year term. It was then developed in a partnership between Stahaken Development Ltd. and the Municipality of Delta. As such it is commonly thought of and serviced in the same manner as other subdivisions in the community of Tsawwassen. Stahaken residents are represented by the Stahaken Homeowners Association.
Tsawwassen had a population of 20,933 in the 2006 census.
