2023–24 United Counties League

The 2023–24 season was the 117th in the history of the United Counties League, a football competition in England. The United Counties League operates three divisions in the English football league system, the Premier Divisions North and South at Step 5 and Division One at Step 6.

The allocations for Steps 5 and 6 this season were announced by The Football Association on 15 May 2023. Starting this season, the two Step 5 divisions in the league promote two clubs each; one as champions and one via a four-team play-off. This replaced the previous inter-step play-off system.
