2023–24 Cymru North

The 2023–24 Cymru North season (also known as the 2023–24 JD Cymru North season for sponsorship reasons) was the fourth season of the second-tier northern region football league in the Welsh football pyramid.

The runners-up (Flint Town United) were promoted to the 2024–25 Cymru Premier (after league winners Holywell Town were refused a promotion licence). The bottom three teams (Chirk AAA, Llanidloes Town, and Porthmadog) were relegated to either the 2024–25 Ardal NE or 2024–25 Ardal NW.

Teams
The league consisted of 16 clubs - 11 teams remaining from the previous season, two teams relegated from the 2022–23 Cymru Premier, and three promoted from the Ardal Leagues.

Airbus UK Broughton and Flint Town United, who are both based in the North, were relegated from the 2022–23 Cymru Premier. Llanidloes Town were saved from having to move to the Cymru South, with the league board deciding to change the Cymru North into a 17-team league. However, on the 20th of June, Cefn Druids announced their withdrawal from the league, following the decision of their playing squad and staff to leave the club a few weeks prior thus reverting the league to its regular 16-team format.

Three teams were promoted from the Ardal Leagues, with Caersws and Denbigh Town promoted as champions of the 2022–23 Ardal NE and 2022–23 Ardal NW respectively. Bangor 1876 were promoted to the second tier for the first time, after defeating Cefn Albion in a promotion play-off. They replaced the relegated Cymru North teams of Conwy Borough, Holyhead Hotspur, and Penrhyncoch.
