Rupert's Land, or Prince Rupert's Land, was a territory in British North America which comprised the Hudson Bay drainage basin. The right to "sole trade and commerce" over Rupert's Land was granted to the Hudson's Bay Company (HBC), based at York Factory, effectively giving that company a commercial monopoly over the area. The territory operated for 200 years from 1670 to 1870. Its namesake was Prince Rupert of the Rhine, who was a nephew of King Charles I and the first governor of HBC. In December 1821, the HBC monopoly was extended from Rupert's Land to the Pacific coast.

British North America comprised the colonial territories of the British Empire in North America from 1783 onwards. English colonisation of North America began in the 16th century in Newfoundland, then further south at Roanoke and Jamestown, Virginia, and more substantially with the founding of the Thirteen Colonies along the Atlantic coast of North America.
