Cwmamman United started its history in 1976 in the Neath & District League Division Three. In Season 1981–82 Cwmamman entered a reserve side in Division Four of the same league. Further success came for the first team as they were once again promoted to Division One in the 1983–84 season. It wasn’t long before (season 1985–86) when Cwmamman were promoted to the Premier League. The next few seasons were an up and down affair with relegation from the premier being followed by promotion back to the premier. Cwmamman were then relegated once more and didn’t return to the Premier until season 1998–99 and in that season finished runners-up and played in a playoff game against Garden Village to enter the Welsh Football League which they lost 3–0 after extra time. Cwmamman finally won the Premier Division in season 2001–02 and then entered the Welsh League for season 2002–03. Cwmamman were relegated in season 2010–11 after finishing 4th from bottom and were relegated due to the restructuring of the Welsh League.
In 2017, Cwmamman reached Division One of the Welsh Football League for the first time after winning promotion.
