Counties 1 Midlands East (South) (formerly Midlands 2 East (South)) is a level 7 English Rugby Union league and level 3 of the Midlands League, made up of teams from the southern part of the East Midlands region including sides from Bedfordshire, Leicestershire, Northamptonshire and occasionally Cambridgeshire and Oxfordshire. When this division began in 1992 it was known as Midlands East 1, until it was split into two regional divisions called Midlands 3 East (North) and Midlands 3 East (South) ahead of the 2000–01 season. Further restructuring of the Midlands leagues ahead of the 2009–10 season, saw it changed to Midlands 2 East (South) and post the RFU's Adult Competition Review, from season 2022–23 it adopted its current name.
The current champions are Stamford.
