Following the RFU's Adult Competition Review, from season 2022-23 it adopted its current name Counties 2 Hampshire.

Each year some of the clubs in this division also take part in the RFU Junior Vase - a level 9-12 national competition.

Departing were Guernsey Vikings, Sandown & Shanklin and Basingstoke, all promoted to Counties 1 Hampshire.

Joining were Havant III, Isle Of Wight, Fareham Heathans, all promoted, and Petersfield II.

Joining were Guernsey Vikings, Locksheath Pumas and Winchester II, all promoted, and Basingstoke, relegated.

Alton finished 11th in Counties 1 Hampshire the previous season and would also have been relegated too but declined to compete in the RFU leagues in 2023-24.

This was the first season following the RFU Adult Competition Review[1] with the league adopting its new name of Counties 2 Hampshire.

The cancellation of National 5 South at the end of the 1995–96 season meant that Hampshire 1 reverted to being a tier 8 league.

The introduction of London 4 South West ahead of the 2000–01 season meant Hampshire 1 dropped to become a tier 9 league with promotion to this new division.

Since the 2000–01 season there has been a play-off between the runners-up of Hampshire Premier and Surrey 1 for the third and final promotion place to London 3 South West.
