The Tees Valley is a city region and combined authority area in the North East of England nestled between North Yorkshire and County Durham and consisting of the following five unitary authorities: Darlington, Hartlepool, Middlesbrough, Redcar and Cleveland and Stockton-on-Tees, the latter four previously formed the non-metropolitan county of Cleveland between 1974 and 1996. Much of the area formed the County Borough of Teesside before 1974.
The Tees Valley area covers the lower, flatter (and much more urban) area of the valley of the River Tees. Tees Valley Enterprise Zone is an enterprise zone which encourages industrial development in 12 sites around the region, with a thirteenth site planned.
The five councils announced plans to establish a Tees Valley Combined Authority after a majority of the public voted for the move. Sixty five per cent of more than 1,900 responses received during a seven-week long public consultation were in favour of a combined authority. The Combined Authority went live on 1 April 2016 (20 years to the day since the abolition of Cleveland) after Local Government Minister James Wharton MP signed the necessary Order.

Tees Valley Enterprise Zone was initiated by the local enterprise partnership Tees Valley Unlimited and its creation was announced by the government in 2011. At its launch, the zone contained 12 sites. Four of these sites offer enhanced capital allowances, aimed at large manufacturers. These sites are Wilton International and South Bank Wharf, both in Redcar and Cleveland, Port Estates in Hartlepool and New Energy and Technology Park in Billingham, Stockton-on-Tees. The remaining sites offer reduced business rates. In March 2015 the government announced that a thirteenth site is to be added, South Bank Wharf Prairie, aimed at oil and gas decommissioning business.
The official region consists of the following unitary authorities:
