2023–24 Southern Combination Football League

The 2023–24 Southern Combination Football League season was the 99th in the history of the competition, which lies at levels 9, 10 and 11 (steps 5 and 6, and county feeder) of the English football league system.

The constitution was announced on 15 May 2023. Starting this season, the Premier Division (Step 5) in the league promotes two clubs; one as champions and one via a four-team play-off. This replaced the previous inter-step play-off system. For this season only, there was only one club relegated from the division.
