Counties 1 Herts/Middlesex (formerly London 2 North West) is a tier 7 English Rugby Union league. It is organised by the London and South East Division Rugby Football Union and is the top-tier competition for clubs in Hertfordshire and parts of north-west London that traditionally was encompassed by the historic county of Middlesex. It was previously known as London 2 North West. After the restructuring of the English rugby union system ahead of the 2022–23 season, the league was renamed to Counties 1 Herts/Middlesex.
Each year the two Hertfordshire clubs in this division with the best record against other Hertfordshire clubs also take part in the Hertfordshire Presidents' Cup, the highest level county cup competition in Hertfordshire. Promoted teams typically go up to Regional 2 Thames while relegated teams drop to Counties 2 Herts/Middlesex.
