2023–24 Cymru Premier

The 2023–24 Cymru Premier (Uwch Gynghrair Cymru 2023–24; known as the JD Cymru Premier for sponsorship reasons) was the 32nd season of the Cymru Premier (formerly known as the Welsh Premier League), the highest football league within Wales since its establishment in 1992.

The winners (The New Saints, their third consecutive title win and sixteenth overall) qualified for the 2024–25 Champions League first qualifying round. The runners-up (Connah's Quay Nomads), third-placed team (Bala Town), and play-off winners (Caernarfon Town) qualified for the 2024–25 Conference League first qualifying round. The bottom two teams (Colwyn Bay and Pontypridd United) were relegated to either the 2024–25 Cymru North or the 2024–25 Cymru South.

Teams
The league consisted of twelve teams; the top ten teams from the previous season, and one team each promoted from the second-tier leagues, the Cymru North and Cymru South. The New Saints entered the season as defending champions (for the second consecutive season).

The two promoted sides were Colwyn Bay (winners of the 2022–23 Cymru North) and Barry Town United (winners of the 2022–23 Cymru South). Barry Town United were promoted back to the top tier on the first time of asking following their relegation in the 2021–22 season, while Colwyn Bay were promoted to the top tier of Welsh football for the first time since switching from the English football league system in 2018–19.

The bottom two teams from the 2022–23 season (Airbus UK Broughton and Flint Town United) were both relegated to the Cymru North for the 2023–24 season. Flint Town United's relegation was only confirmed on the final day of the previous season, where a dramatic victory for Aberystwyth Town, combined with Flint's defeat to Pontypridd United, saw the Silkmen drop into the relegation zone.

Haverfordwest County came close to being relegated following their failure to achieve a Tier One license at the first time of asking, but their appeal was successful, ensuring their stay in the league.

Matches 1–22
Teams played each other twice, once at home and once away.

Matches 23–32
After 22 matches, the league split into two groups (the top six and the bottom six). Each team plays every other team in their group twice (once at home and once away).

Conference League play-off
Teams placed 3rd-7th will enter one-off play-off matches for the third spot in the Conference League first qualifying round. The higher-placed team gains home advantage. Since the 2023–24 Welsh Cup winners finished in the top three, the 3rd-placed team qualified automatically for the Conference League and the spot was vacated.
