The Cymru South [1] is a regional football league in Wales, covering the southern half of the country. It initially had clubs with semi-professional status. Together with the Cymru North, it forms the second tier of the Welsh football league system.
The first year of its operation was in 2019–20 with the Football Association of Wales owning and administering the tier 2 leagues for the first time. These changes followed on from a review of the Welsh Football Pyramid. [2] Prior to 2019, the equivalent league was the Welsh Football League Division One, covering South Wales.
