2023–24 Ardal SE

The 2023–24 Ardal SE season (also known as the 2023–24 Floodlighting and Electrical Services Ardal SE season for sponsorship reasons) was the third season of the new third-tier southern region football in Welsh football pyramid, part of the Ardal Leagues.

The winners (Trethomas Bluebirds) were promoted to the 2024–25 Cymru South. The runners-up (Newport City) were also promoted after winning the Ardal Southern play-off. The bottom two teams (Hay St Marys and Lliswerry) and Aberbargoed Buds (who withdrew after the completion of the season) were relegated to Tier 4.

Teams
The league was made up of sixteen teams; twelve teams remaining from the previous season, three teams promoted from Tier 4, and one team transferred from the 2022–23 Ardal SW.

The teams promoted from Tier 4 were Aberbargoed Buds and Abercarn United from the Gwent County League Premier Division, and Hay St Marys from the Mid Wales Football League South Division (replacing the relegated Ardal SE teams of Croesyceiliog, Monmouth Town, and RTB Ebbw Vale). Since no team was relegated from the 2022–23 Cymru South, Treharris Athletic Western were transferred from the Ardal SW (replacing the promoted Ardal SE team of Abertillery Bluebirds).
