The British colonization of the Americas is the history of establishment of control, settlement, and colonization of the continents of the Americas by England, Scotland and, after 1707, Great Britain. Colonization efforts began in the late 16th century with failed attempts by England to establish permanent colonies in the North. The first of the permanent English colonies in the Americas was established in Jamestown, Virginia, in 1607. Approximately 30,000 Algonquian peoples lived in the region at the time. Colonies were established in North America, Central America, South America, and the Caribbean. Though most British colonies in the Americas eventually gained independence, some colonies have remained under Britain's jurisdiction as British Overseas Territories.

The Jamestown settlement in the Colony of Virginia was the first permanent English settlement in the Americas. It was located on the northeast bank of the James River, about 2.5 mi (4 km) southwest of the center of modern Williamsburg. It was established by the Virginia Company of London as "James Fort" on May 4, 1607 O.S., and was considered permanent after a brief abandonment in 1610. It followed several failed attempts, including the Lost Colony of Roanoke, established in 1585 on Roanoke Island, later part of North Carolina. Jamestown served as the colonial capital from 1616 until 1699. Despite the dispatch of more settlers and supplies, more than 80 percent of the colonists died in 1609–1610, mostly from starvation and disease. In mid-1610, the survivors abandoned Jamestown, though they returned after meeting a resupply convoy in the James River.
