The 2021–22 Cymru South season (also known as the 2021–22 JDCymru South season for sponsorship reasons) was the third season of the second-tier Southern region football in Welsh football pyramid. Teams will play each other twice on a home and away basis.
Pre-season favourites Ammanford AFC endured a season of struggle, with a three way title race for much of the season between Briton Ferry, Pontypridd Town AFC, and Llantwit Major AFC. After all three clubs lead at some point, Llantwit Major put together an outstanding finish to the season, winning 11 games out of 12 to lift the trophy with a game to spare. Pontypridd finished 2nd, and were promoted after Llantwit were controversially denied a Tier 1 license.[1]

^The match between Carmarthen and Risca on 31 July 2021 was cancelled due to COVID-19 cases in Carmarthen. However, it was later deemed that Carmarthen had sufficient players to fulfil the fixture in line with the league's policy, and were therefore deducted 3 points and fined £1,000.[10]
