The Cymru Premier is an association football league based in Wales. Formed in 1992 as the League of Wales, it was the first national football league in the country. The competition changed its name to the Welsh Premier League in 2002 and then to the Cymru Premier in 2019. In its inaugural season 20 teams played in the league, but it has been restructured since and has 12 member clubs in the 2024–25 season. Although it is the highest level of the Welsh football league system, the Welsh Premier League does not include the country's four largest professional clubs, Cardiff City, Swansea City, Wrexham and Newport County; for historical reasons these clubs all play within the English league system. As of 2024, The New Saints, who have played in Oswestry in England since 2005, are the only full-time professional team in the league. Many of the clubs that have played in the league were founded in the 19th century and spent a century or more playing in regional leagues before the creation of the League of Wales in 1992.

Since its formation, 42 clubs have taken part in the league. The only clubs to have played in the league in every season since it was formed are Aberystwyth Town and Newtown. Conversely two other founder members, Abergavenny Thursdays and Llanidloes Town, were relegated at the end of the league's inaugural season and have never returned. Two other clubs, Llangefni Town and Cardiff Grange Harlequins, have spent only a single season in the league. The most recent team to make its debut in the league was Colwyn Bay, who gained promotion to the league for the first time in 2023. A system of promotion and relegation exists between the Cymru Premier and the two regional leagues at the second level of the Welsh league system, the Cymru North in the northern half of the country and the Cymru South in the southern half.

The table shows the first and most recent season in which each club competed in the league up to and including the 2023–24 season. Some clubs' membership was intermittent between their first and last season. The name shown for each club is the most recent, and the table is initially sorted in alphabetical order of these names. Any other names under which the club played in the league are shown in footnotes. A dagger symbol (†) indicates that the club was a founder member of the league.
