Current holders: Haverhill Rovers

The Under-18 Midweek Cup is open to all under-18 sides who play in midweek competitions. 

The competition has been run since the 2014-15 season. For the two seasons prior to that, teams competed in a Boys' Under-18 Cup/Sunday Cup competition, before it was decided to split Sunday sides and midweek sides into separate competitions.

AFC Sudbury won the competition seven seasons in a row that it was played (the competition was not completed due to Covid in the 2019-20 season) before Haverhill Rovers broke the sequence by winning the 2024-24 final versus Bury Town, who had knocked out AFC Sudbury in the semi-finals.
