Cumberland (unitary authority)

Cumberland is a unitary authority area in Cumbria, England, and a non-metropolitan county and district. It borders Scotland, Northumberland, Westmorland and Furness, and the Irish Sea. Part of the area is in the Lake District National Park and notable landmarks include Carlisle Cathedral, Carlisle Castle and Hadrian's Wall.

In comparison to the historic county of Cumberland that existed before 1974, the district covers 77% of its area (excluding Penrith area) and 90% of its population. When created, in April 2023, it took over the northern and western part of the 1974–2023 Cumbria non-metropolitan county's administration and the corresponding former Allerdale, Carlisle and Copeland districts, while the new Westmorland and Furness unitary authority took over the remainder.
