The 2016–17 season saw AFC Wimbledon compete in League One for the first time in their history. They remained unbeaten in the South London derby fixtures, recording two draws against Millwall, a home draw against Charlton Athletic, and a 2–1 away win at The Valley on 17 September 2016. Promotion also placed AFC Wimbledon in the same division as Milton Keynes Dons, who had simultaneously been relegated from the Championship. This ensured the club would face Milton Keynes Dons for the first time at Kingsmeadow which they did on 14 March 2017, going on to triumph 2–0. The club ultimately finished 15th in the league, after a disappointing slump saw them win just five out of their last 22 league matches between January and April.
