MediaCityUK is a 200-acre (81 ha) mixed-use property development site on the banks of the Manchester Ship Canal in Salford and Trafford, Greater Manchester, England. The project is being developed by Peel Media, and its principal tenants are media organisations and the University of Salford. The land occupied by the development was part of the Port of Manchester and Manchester Docks.

The BBC signalled its intention to move jobs to Manchester in 2004, and the Salford Quays site was chosen in 2006. The Peel Group was granted planning permission to develop the site in 2007, and construction of the development, with its own energy generation plant and communications network, began the same year. Based in Quay House, the principal tenant is the BBC, whose move marks a large-scale decentralisation from London. ITV Granada completed the first phase of its move to MediaCityUK on 25 March 2013, followed in two stages by the northern arm of ITV Studios: the second stage involved Coronation Street being moved to a new production facility on Trafford Wharf (next to the Imperial War Museum North) at the end of 2013. The Studios on Broadway houses seven high-definition studios, claimed to be the largest such facility in Europe.
