Point Roberts is a pene-exclave of Washington on the southernmost tip of the Tsawwassen peninsula, south of Vancouver, British Columbia. The area, which had a population of 1,191 at the 2020 census, is reached by land from the rest of the United States by traveling 25 mi (40 km) through Canada. It is a census-designated place in Whatcom County, Washington, with a post office, and a ZIP Code of 98281. Direct sea and air connections with the rest of the U.S. are available across Boundary Bay. Point Roberts was created when the United Kingdom and the United States settled the Pacific Northwest American-Canadian border dispute in the mid-19th century with the Oregon Treaty. The two parties agreed that the 49th parallel would define the boundary between their respective territories, and the small area that incorporates Point Roberts is south of the 49th parallel. Questions about ceding the territory to the United Kingdom and later to Canada have been raised since its creation; however, its status has remained unchanged.

The Point Roberts–Boundary Bay Border Crossing connects the communities of Point Roberts, Washington, and Tsawwassen, British Columbia on the Canada–US border.

The sea stretches from the channels of the Discovery Islands north of the Strait of Georgia to Budd Inlet at the south end of Puget Sound. It is partially separated from the open Pacific Ocean by Vancouver Island and the Olympic Peninsula. Much of the coast is part of the Pacific Northwest megalopolis. The region is anchored by Metro Vancouver to the north, and Metro Seattle to the south. Other principal cities on the Salish Sea include Bellingham, Port Angeles, Port Townsend, Everett, Tacoma, Olympia, and Bremerton in Washington, and Victoria and Nanaimo in British Columbia.

The Point Roberts Light is an aid to navigation located in Point Roberts, Whatcom County, Washington State, United States. The skeletal structure overlooks the Strait of Georgia from the end of a peninsula extending southward from Delta, British Columbia, Canada, across the 49th parallel into the U.S. It is part of Lighthouse Marine Park, a 21-acre (8.5 ha) recreational area operated by Whatcom County Parks and Recreation.In 1908, the federal government bought 21 acres (8.5 ha) at the end of the peninsula for a light station. A true lighthouse was never built and the land was transferred to Whatcom County for use as a county park. In 2000, the Point Roberts Lighthouse Society was formed with the purpose of building a proper lighthouse on the point. According to a 2014 presentation to the Whatcom County Parks and Recreation Committee, the society has completed architectural designs and has funding in place with the goal of seeing the project, which would include a U.S. Coast Guard-approved navigational light, through to completion in 2015.

Tsawwassen (English: tə-WAH-sən) is a suburban, mostly residential community on a peninsula in the southwestern corner of the City of Delta in British Columbia, Canada. It provides the only road access to the American territory on the southern tip of the peninsula, the community of Point Roberts, Washington, via 56th Street. It is also the location of Tsawwassen Ferry Terminal, part of the BC Ferries, 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 (Roberts Bank), the ferry terminal is built at the southwestern end of a 3 km (1.9 mi) causeway (part of Highway 17) that juts into the Strait of Georgia. Boundary Bay Airport, a major training hub for local and international pilots which also provides local airplane and helicopter service, is ten minutes away. The Roberts Bank Superport is also nearby. To the northwest of the community are the lands of Tsawwassen First Nation ("TFN"), a people of Coast Salish ancestry who have used this land since at least 200 B.C. Having been "stripped of their lands, rights and resources" by European colonizers throughout the 19th century, and in accordance with a 2009 treaty with British Columbia, their territory now consists of approximately 724 ha (1,790 acres) of treaty settlement land, 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.
