Radnorshire (Welsh: Maesyfed) was one of three districts of the county of Powys, Wales, from 1974 - 1996. The district had an identical area to the previous administrative county of Radnorshire. The district was formed as Radnor on 1 April 1974 as part of a general reorganisation of local government in England and Wales under the Local Government Act 1972. The new district replaced eight local authorities: * The urban districts of Knighton, Llandrindod Wells and Presteigne * The rural districts of Colwyn, Knighton, New Radnor, Painscastle and Rhayader.
