The South Wales Senior League is a former football league in South Wales. The league consisted of two divisions, named Divisions One and Two. Division One was a feeder to the Welsh Football League Division Three, and therefore sat at levels 5 of the Welsh football pyramid.
The league was dominated by clubs from Cardiff with no fewer than 14 titles going to the city. Bridgend Street won it four times and their success in 2011 saw them move up into the Welsh Football League for the first time.
