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

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

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

However, the introduction of London 4 South West ahead of the 2000–01 season meant that clubs were relegated into this new division instead of into Hampshire 1 or Surrey 1.

On 4 April 2020 the RFU announced that a "best playing record formula" would be used to determine promotion and relegation and there would be no play-offs.
