London 2 South East is an English level 7 Rugby Union League.

[1] When this division began in 1987 it was known as London 3 South East, changing to its current name ahead of the 2009–10 season.

Each year all clubs in the division also take part in the RFU Intermediate Cup - a level 7 national competition.

Promotion continued to London 2 South, and relegation to either Kent 1 or Sussex 1.

However, the introduction of London 4 South East ahead of the 2000–01 season meant that clubs were now relegated into this new division instead of into Kent 1 or Sussex 1.
