Regional 2 South East is an English level 6 rugby union regional league for rugby clubs in London and the south-east of England including sides from East Sussex, south Greater London, Hampshire, Kent, Surrey and West Sussex. When this division began in 1987 it was known as London 2 South, changing to London 1 South ahead of the 2009–10 season. Following the RFU Adult Competition Review the league was decreased in size from 14 to 12 and the name changed once more.
