2023–24 Ardal NW

The 2023–24 Ardal NW season (also known as the 2023–24 Lock Stock Ardal NW season for sponsorship reasons) was the third season of the new third-tier northern region football league in the Welsh football pyramid, part of the Ardal Leagues.

The winners (Flint Mountain) were promoted to the 2024–25 Cymru North. The runners-up (Llay Welfare) were also promoted after winning the Ardal Northern play-off. The bottom three teams (Bethesda Athletic, Hawarden Rangers, and Saltney Town) were relegated to Tier 4.

Teams
The league was made up of sixteen teams; ten teams remaining from the previous season, four teams promoted from Tier 4, and two teams relegated from the 2022–23 Cymru North.

The teams promoted from Tier 4 were St Asaph City and Llannefydd from the North Wales Coast East Football League Premier Division, and Bethesda Athletic and Pwllheli from the North Wales Coast West Football League Premier Division (replacing the relegated Ardal NE team of Rhostyllen, the withdrawn Ardal NE teams of Bodedern Athletic and Rhydymwyn, and the folded team of Llandudno Albion). The teams relegated from the Cymru North were Conwy Borough and Holyhead Hotspur (replacing the promoted Ardal NE teams of Denbigh Town and Bangor 1876).
