Immingham is a town, civil parish and ward in the North East Lincolnshire unitary authority of England. It is situated on the southwest bank of the Humber Estuary, and is 6 miles (10 km) north-west from Grimsby.

The region was relatively unpopulated and undeveloped until the early 1900s, when the Great Central Railway began developing its Immingham Dock; as a consequence of the dock development, and of nearby post-Second World War large scale industrial developments Immingham developed from a minor place into a significant town during the 20th century.
