London Spitfire is a professional Overwatch team representing the city of London, United Kingdom. The Spitfire compete in the Overwatch League (OWL) as a member of the league's West region. Founded in 2017, London Spitfire is one of the league's twelve founding members and is the only professional Overwatch team representing a European city. The team is owned by Jack Etienne and the esports organization Cloud9, who also own British Hurricane, an academy team for the Spitfire that competed in Overwatch Contenders (OWC).

The Overwatch League (OWL) was a professional esports league for the video game Overwatch, produced by its developer, Blizzard Entertainment. From 2018 to 2023, the Overwatch League followed the model of other traditional North American professional sporting leagues by using a set of permanent, city-based teams backed by separate ownership groups. The league used the regular season and playoffs format rather than promotion and relegation used commonly in other esports and non-North American leagues, with players on the roster being assured a minimum annual salary, benefits, and a portion of winnings and revenue-sharing based on team performance.
