Counties 2 Hertfordshire (formerly Counties 2 Herts/Middlesex and before that London 3 North West) is a level 8 league within the RFU league structure and is made up of teams predominantly from north-west London and Hertfordshire. Promoted sides move up to Counties 1 Hertfordshire while relegated teams drop to Counties 3 Hertfordshire. Following the RFU's Adult Competition Review, from season 2022–23 it adopted the name Counties 2 Herts/Middlesex (2022–25), however ahead of the 2025–26 season a decision was taken to split out Hertfordshire RFU and Middlesex RFU clubs for the first time, with Middlesex teams moving on a level transfer to Counties 2 Middlesex.
