Ceredigion District Council was one of six district-level authorities in the county of Dyfed, Wales, from 1974 until 1996. The district had an identical area to the pre-1974 administrative county of Cardiganshire. From its creation in 1974 the district used the name "Ceredigion" rather than "Cardiganshire", which had been used for the former county council. Further local government reorganisation in 1996 saw Dyfed County Council abolished and Ceredigion become a unitary authority, with the district council taking over county-level services to become Ceredigion County Council.
