3 Mills Studios is a centre for film, television and theatre production near Stratford in East London. The site of a former distillery in Three Mills became a dedicated centre for television and film production work with the establishment in the 1980s of Bow Studios, Three Mills Island Studios, and Edwin Shirley Productions. In the mid-1990s, the three studios merged to become 3 Mills Studios, under the management of Workspace Group.

The Three Mills are former working mills and an island of the same name on the River Lea. It is one of London’s oldest surviving industrial centres. The mills lie in the London Borough of Newham, but despite lying on the Newham side of the Lea, access is principally from the western, London Borough of Tower Hamlets, side of the river.
