2023–24 Eastern Counties Football League

The 2023–24 Eastern Counties Football League is the 81st season in the history of the Eastern Counties Football League, a football competition in England. Teams are divided into three divisions, the Premier Division at Step 5, and the geographically separated Division One North and Division One South (Eastern Senior League), both at Step 6 of the English football league system.

The constitution was announced on 15 May 2023. Starting this season, the two step 5 divisions in the league will each promote two clubs; one as champions and one via a four-team play-off. This replaces the previous inter-step play-off system. For this season only, there will be only one club relegated from each of the two step 5 divisions.
