Tier 1: Cymru Premier

At the top is the Cymru Premier, which is the only national league in Wales and is run by the Football Association of Wales.

Tier 2: Cymru North and Cymru South

Since 2019–20, the Football Association of Wales runs the second tier for the first time after a review of the Welsh league pyramid. Tier 2 is split into a north and central Wales league, Cymru North, and a corresponding league for south Wales, Cymru South. The champions of each of these leagues can be promoted to the Cymru Premier, subject to acceptable ground facilities, and if the champions cannot meet the criteria the runner-up team may be considered.

The Cymru North replaced the Cymru Alliance whilst the Cymru South incorporated most of the clubs of the then-highest division of the Welsh Football League.

Tier 3: Ardal Leagues

Since the 2020–21 season, the Football Association of Wales has run the third tier after a review of the Welsh league pyramid. Tier 3, called the Ardal Leagues is split into a Northern and Southern League, with each league divided into two regionally based divisions, giving North East, North West, South East and South West leagues, each consisting of a maximum of 16 clubs. In an attempt to avoid dividing the current Mid-Wales teams across all four leagues, the North-East league contains a large contingent of the Mid-Wales teams. The North-West league contains the sides near the North Wales coast. To be eligible to join the league, clubs need to meet the criteria for FAW tier 3 certification.

The Ardal Leagues structure replaces the former tier 3 leagues: Welsh Football League Division One, Mid Wales Football League Division One, Welsh Alliance League Division 1 and the Welsh National League Premier Division, leagues based in South Wales, Mid Wales, North West Wales and North East Wales respectively.

There are three relegated clubs from each of the tier 3 leagues at the end of each season.

Tier 4: Area leagues

Below this are six local tier 4 leagues, each run by one of the area associations of Welsh football:

• Central Wales League (run by Central Wales Football Association)
• North East Wales Football League Premier Division (run by North East Wales Football Association)
• North Wales Coast East Football League Premier Division and North Wales Coast West Football League Premier Division (run by North Wales Coast Football Association)
• Gwent County League Premier Division (run by Gwent County Football Association)
• West Wales Premier League (run by the West Wales Football Association)
• South Wales Alliance League Premier Division (run by South Wales Football Association)

The winners of each league are eligible for promotion to the Ardal Leagues subject to meeting FAW tier 3 certification. In the event that winners do not meet the criteria, the runner-up is also eligible for promotion, again subject to meeting the same tier 3 certification requirements.
