Dearham is a village and civil parish in Cumbria, historically part of Cumberland, near the Lake District National Park in England. It lies about 2 miles (3.2 km) east of Maryport and 5 miles (8.0 km) west of Cockermouth. At the 2021 census, the parish had a population of 2,151.

'Dearham' is an Old Anglian compound of 'dēor' and 'hām'. Old Anglian is Old English. 'Dēor' means 'deer', 'hām' is 'homestead' or 'village' or 'estate'.

With its resources of coal and easy access to railways, Dearham is part of Cumberland's former coal mining industry. It saw its population increase from 515 in 1821 to 2,598 in 1891 due to the expansion of coal mining. However, with the decline of deep mining and, later, open cast working, the coal industry ceased to be a source of employment in the area.

Historically, Dearham was in the Workington division of the County of Cumberland, in the ward of Allerdale below Derwent. It belonged to the Derwent Petty sessional division, Cockermouth Union and the County Court district of Cockermouth and Workington.

The village also belongs to the rural deanery of Maryport, the Archdeacon of West Cumberland and the Diocese of Carlisle.

Dearham is part of the Penrith and Solway constituency since 2024, and has been represented by Markus Campbell-Savours of the Labour Party since the 2024 general election. Prior to 2024, the town was part of the parliamentary constituency of Workington, which was abolished in the 2023 boundary review.

For Local Government purposes it is in the Cumberland unitary authority area.

Dearham has its own Parish Council; Dearham Parish Council.
