London 2 South West is an English level 7 Rugby Union League. 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. The division is made up of teams predominantly from south-west London, Surrey, and Hampshire. The 12 teams play home and away matches from September through to April. Each year all clubs in the division are also invited to take part in the RFU Intermediate Cup - a level 7 national competition.

Promoted teams move up to London 1 South with league champions going up automatically and the runners up playing a playoff against the runners up from London 2 South East while demoted teams usually drop down to London 3 South West.

The teams competing in 2021-22 achieved their places in the league based on performances in 2019-20, the 'previous season' column in the table below refers to that season not 2020-21.

Old Tonbridgians who finished 10th in 2019-20 were unable to fulfil their fixtures in and withdrew from the league in November 2021. Later the same month London Exiles, who finished 9th in 2019-20, also withdrew from the league having played only one match.

On 30 October the RFU announced that a decision had been taken to cancel Adult Competitive Leagues (National League 1 and below) for the 2020/21 season meaning London 2 South West was not contested.

Departing were KCS Old Boys promoted as champions to London 1 South whilst Gosport & Fareham (11th) and Effingham & Leatherhead (12th) were relegated to London 3 South West.
