Whitehaven is a town and civil parish in the Cumberland district of Cumbria, England. It is a port on the north-west coast, and lies 4 miles (6 km) outside the Lake District National Park. It is 35 miles (56 km) south-west of Carlisle. The parish also includes the small village of Sandwith. At the 2021 census the parish had a population of 24,040 and the Whitehaven built up area had a population of 22,945.
The town's growth was largely due to the exploitation of the extensive coal measures by the Lowther family, driving a growing export of coal through the harbour from the 17th century onwards. It was also a major port for trading with the American colonies, and was, after London, the second busiest port of England by tonnage from 1750 to 1772. This prosperity led to the creation of a Georgian planned town in the 18th century which has left an architectural legacy of over 170 listed buildings.
