South West 1 East is an English, level six, rugby union league in south and south-west England; mainly Bedfordshire, Berkshire, Buckinghamshire, Dorset, Gloucester, Northamptonshire, Oxfordshire, Warwickshire and Wiltshire. Originally a single division known as South West 2, since 1996 the division has been split into two regional leagues – South West 1 East and South West 1 West.
The champions are promoted to South West Premier (formerly National League 3 South West) and the runner-up play the second team in South West 1 West, with the winning team gaining promotion. Relegated sides usually play in one of the two seventh-tier leagues (depending on location) – Southern Counties North or Southern Counties South.
