Current holders: Walsham-le-Willows

The Senior Reserve Cup was started in the 2006-07 season. It is a competition for the reserve teams of clubs whose first team play in the Premier or Senior cups unless the reserve team itself plays senior football. In this case the reserve team plays in the Senior Cup and the first team in the Premier Cup.

Not surprisingly, no club has dominated this competition with only Lowestoft Town Reserves, Felixstowe and Walton United Reserves (the first and current holders) and Walsham-le-Willows winning the cup twice.

The biggest win occurred in the first final when Felixstowe and Walton United beat Southwold Town Reserves 5-1.

Only once has it not been won within the standard 90 minutes and that was in 2015 when Hadleigh United Reserves beat Crane Sports Reserves 4-2 on penalties following a 4-4 draw after extra time.
