New towns in the United Kingdom

The new towns in the United Kingdom were planned under the powers of the New Towns Act 1946 and later acts to relocate populations in poor or bombed-out housing following the Second World War. They were developed in three waves. Later developments included the expanded towns: existing towns which were substantially expanded to accommodate what was called the "overspill" population from densely populated areas of deprivation.

Designated new towns were removed from local authority control and placed under the supervision of a development corporation. These corporations were later disbanded and their assets split between local authorities and, in England, the Commission for New Towns (later English Partnerships).
