MediaCityUK is a 200-acre (81 ha) mixed-use property development site at Salford Quays on the banks of the Manchester Ship Canal in Salford and Trafford, England. The project is being developed by Peel Media, and its principal tenants are media organisations. 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 will be the BBC, whose move marks a large-scale decentralisation from London. BBC Children's, BBC Radio 5 Live, BBC Research and BBC Sport are among the departments scheduled to relocate to the development. ITV's Granada division plans to move from its Granada Studios to MediaCityUK in 2012. The Studios on Broadway house seven high-definition studios, claimed to be the largest such facility in Europe.
