Immingham is a town and civil parish in North East Lincolnshire, in Lincolnshire, England. It is situated on the south-west bank of the Humber Estuary, and is 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. The Port of Immingham & Grimsby was the largest port in the United Kingdom by tonnage with 54 million tonnes of cargo passing through in 2019.
The Immingham Ward of North East Lincolnshire Council includes Stallingborough, Healing and Habrough. As of 2018, its elected councillors are Stewart Swinburn (Conservative), David Bolton (Labour), and David Watson (Labour).
Population of the ward in 2001 was 11,804 persons (2001 census), and 11,507 persons in 2011 (2011 census).
European route E22 passes through Immingham on the A180 and A160 via Immingham Dock.
