Clwyd South (Welsh: De Clwyd) was a constituency of the House of Commons of the Parliament of the United Kingdom (Westminster). The constituency was created in 1997, and it elected one Member of Parliament (MP) by the first past the post method of election.

The Clwyd South Senedd constituency was created with the same boundaries in 1999 (as an Assembly constituency).

The constituency was abolished as part of the 2023 Periodic Review of Westminster constituencies and under the June 2023 final recommendations of the Boundary Commission for Wales. Its wards were split between Clwyd East, Dwyfor Meirionnydd, Montgomeryshire and Glyndŵr, and Wrexham.^[2]

The constituency straddled the authorities of Denbighshire and the borough of Wrexham. Main population centres included the suburbs of Ruabon, Chirk, Rhosllannerchrugog, Cefn Mawr and Coedpoeth to the south of the city of Wrexham, in addition to Llangollen and Corwen further up the Dee valley to the west. Until the 2010 election, the constituency included a small part of the preserved county of Powys. This anomaly was resolved by the Boundary Commission for Wales with the boundaries first used in 2010.

The constituency comprised the following electoral wards:

• From Wrexham: Overton, Bronington, Dyffryn Ceiriog/Ceiriog Valley, Chirk North, Gwenfro, Johnstown, Llangollen Rural, Marchwiel, Penycae, Penycae and Ruabon South, Plas Madoc, Ponciau, Ruabon, Bryn Cefn, Minera, Brymbo, Coedpoeth, Cefn, Chirk South, Esclusham, New Broughton, Pant
• From Denbighshire: Corwen, Llangollen, Llandrillo
