Clwyd is a preserved county of Wales, situated in the north-east, bordering England with Cheshire to its east, Shropshire to the south-east, and the Welsh counties of Gwynedd to its immediate west and Powys to the south.

It additionally shares a maritime border with the metropolitan county of Merseyside along the River Dee. Between 1974 and 1996, it was a county with a county council, and it was divided into six districts. It is named after the River Clwyd, which runs through the region. It was also a Royal Mail postal county before the postal county scheme was abolished in 1996. Clwyd County Council was based in the county town of Mold.


Clwyd is bordered by the preserved/ceremonial counties of Gwynedd to the West, Powys to the South, Shropshire to the South East, Cheshire to the East and Merseyside over the River Dee. Since the 2003 boundary changes, its coastline has extended from the Dee Estuary in Flintshire through to Llanfairfechan in Conwy.

The east of the county is fairly urbanised, particularly areas such as Wrexham, Deeside and the commuter settlements close to Chester. The west, however is more rural, with Snowdonia National Park in eastern areas of Conwy. Large coastal settlements include Rhyl and Prestatyn in Denbighshire, moving westwards to Abergele, Colwyn Bay and Llandudno.

Central areas of Clwyd feature the mountainous Clwydian Range and Berwyn range, and the Vale of Clwyd in the central north is a rich agricultural area. The population as of 2007 is estimated at 491,100, based on figures for the four component unitary authority areas.

Clwyd consists of the whole of the historic county of Flintshire, and most of Denbighshire. Since 2003 it has also included the former district of Aberconwy, which lies in the historic county of Caernarfonshire. Edeyrnion Rural District was also part of Merionethshire.
