Clwyd is a preserved county of Wales. From 1974 until 1996, it was an administrative county, with a county council, and was divided into six districts:
- Alyn and Deeside
It was formed originally in 1974 under the Local Government Act 1972 as a merger of the administrative counties of Flintshire and (most of) Denbighshire, along with the Edeyrnion Rural District from Merionethshire.
For local government purposes, Clwyd was split in 1996 into the unitary authorities of Flintshire, Wrexham County Borough, Denbighshire, and parts of Conwy and Powys.
In 2003, the preserved county of Clwyd was changed to cover the remainder of Conwy (which had previously been part of Gwynedd).
