Counties 3 Midlands East (South North) / (South South) (formerly Midlands 4 East (South) area level 9 English Rugby Union leagues and level 4 of the Midlands League, made up of teams from the southern part of the East Midlands region including clubs from Bedfordshire, Leicestershire, Northamptonshire, Lincolnshire and occasionally Cambridgeshire, all of whom play home and away matches throughout the season. Each year some of the clubs in this division also take part in the RFU Junior Vase - a level 9-12 national competition.
Formed for the 2006-07 season, the division was originally known as Midlands 5 East (South) but changed to its present name for the 2008-09 season due to league restructuring. Further restructuring of the Midlands leagues ahead of the 2009–10 season, saw it changed to Midlands 4 East (South) and post the RFU's Adult Competition Review, from season 2022-23 it adopted its current name. From 2023-24 the league was split into South and Central divisions.
Promoted teams move up to Counties 2 Midlands East (South) and since Midlands 5 East (South) was abolished there has been no relegation.
