Midlands 4 East (South) is a level 9 English Rugby Union league 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. Promoted teams tend to move up to Midlands 3 East (South) and since Midlands 5 East (South) was abolished there has been no relegation.
