Teesside Teesside Teesside () is the conurbation in the north east of England around the urban centre of Middlesbrough that is primarily made up of the towns Billingham, Redcar, Stockton-on-Tees, Thornaby and surrounding settlements near the River Tees. It was the name of a local government district between 1968 and 1974—the County Borough of Teesside. Teesside remains an important centre for heavy industry, although the number of people employed has declined. Traditional industries, primarily steelmaking (British Steel) and chemical manufacture (Imperial Chemical Industries (ICI)), have been replaced to a large extent by high technology activities, science development and service sector roles.

Its flagship developments included the Tees Barrage, Hartlepool Marina, Teesside Park and Teesdale Business Park.
