Appleby (UK Parliament constituency)

Appleby was a parliamentary constituency in the county of Westmorland in England. It existed for two separate periods: from 1295 to 1832, and from 1885 to 1918.

Appleby was enfranchised as parliamentary borough in 1295, and abolished by the Great Reform Act 1832. It returned two Members of Parliament (MPs) using the bloc vote system. It was represented in the House of Commons of England until 1707, in the House of Commons of Great Britain from 1707 to 1800, and finally in the House of Commons of the United Kingdom from 1801 to 1832. Its best-known MP was William Pitt the Younger who became prime minister in 1783 at the age of 24.

For the 1885 general election the Redistribution of Seats Act created a county constituency of the same name, which returned a single MP elected by the first-past-the-post system. The county constituency was abolished at the 1918 general election.
