Mid Wales South League

The Mid Wales South League is an association football league, from Mid Wales at the fifth of the Welsh football league system.
Teams are eligible to be promoted to the Central Wales Football League if standards and facilities fall into line with the regulations of the Mid Wales League.
The league has sometimes written as the "Mid-Wales League ".
In the 2019–20 season, when the season was curtailed due to the coronavirus pandemic, Brecon Corries were champions with a 100% record of 16 wins from 16 games with 143 goals scored and just two conceded. In addition to these statistics the team scored a 27–0 win at Knighton Town Reserves which was expunged from the record books following Knighton’s withdrawal from the league.
In 2022–23 season, only five clubs competed in the league, and at the end of the season the league announced it would not return for the following year. The league planned to revive for the 2024–25 season but this did not materialise but in April 2025 the league confirmed they were planning to return for the 2025–26 season. This was confirmed in August 2025 with twelve teams in the revived league.
