Copeland is a constituency in Cumbria created in 1983 and represented in the House of Commons of the UK Parliament.^{[n 1][n 2]} The constituency is represented in Parliament by Trudy Harrison, of the Conservative Party, since a by-election in February 2017. It was retained at the snap 2017 general election four months later. The seat had been held by Labour candidates at elections between 1983 and 2015 included.

Copeland is one of five Cumbria seats won (held or gained) by a Conservative candidate in 2019 out of a total of six covering the county. The bulk of this seat is in the Lake District, together with a large proportion of its population.

Further to the completion of the 2023 Periodic Review of Westminster constituencies, the seat will be abolished, with the majority being included in a new constituency which will also include the town of Workington, to be named Whitehaven and Workington - to be first contested at the next general election. Keswick will be included in the new constituency of Penrith and Solway, and Millom transferred to Barrow and Furness.^[2]

The sole forerunner to the constituency was the abolished constituency of Whitehaven. Copeland consistently returned Labour Party candidates since its creation in 1983 until the by-election of 23 February 2017, when Trudy Harrison gained it for the Conservatives. Prior to that (save for the landslide in 1931 when part of the parliamentary Labour Party remained in government with the Conservative Party under Ramsay MacDonald), the last Conservative elected for the area was in 1924.

The 2015 result gave the seat the 31st most marginal majority of Labour's 232 seats by percentage of majority.^[3]

Following the renaming of the Whitehaven constituency as Copeland, Jack Cunningham, who had previously been the member for Whitehaven, stood for and won the Copeland seat. Its boundaries remained unchanged, being coterminous with the local government district of Copeland.
