Cariboo District was a federal electoral district in British Columbia, Canada, that was represented in the Canadian House of Commons from 1871 to 1872. It was created when the province of British Columbia joined Confederation in 1871. Like other ridings established in that year, a byelection was called to fill the seat until the general election of 1872. The riding constituted all of the Lillooet and Cariboo Land Districts (identical with the provincial electoral districts of those names at the time), meaning everything north and inland from Howe Sound and north of the Thompson River, all the way to the Yukon border excepting the Coast.
