The Great Britain Davis Cup team has represented the United Kingdom internationally since 1900 in the Davis Cup. Organised by the Lawn Tennis Association (LTA), it is one of the 50 members of International Tennis Federation's European association (Tennis Europe).
The team has won the world cup 10 times and been runner-ups on 8 occasions. It has longstanding rivalries with Australia and the United States. The national team took part in the inaugural Davis Cup in 1900, and has spent 16 years in the World Group. They are the third most successful team in terms of championships won. Despite this success, the team's performance has been inconsistent; between long periods without significant impact in the competition, it has enjoyed its most successful periods in the 1900s, winning five of the first 12 editions of the tournament and four wins in the 1930s with Fred Perry, with a significant resurgence in the mid-2010s with Andy Murray and his brother Jamie culminating in victory in 2015.
Under the current management of Leon Smith, the national team qualified to the World Group in 2013, won the title in 2015, and reached the semi-finals in 2016. In its new tournament format, Great Britain and Australia were invited to the new 2019 Davis Cup Finals as a wild card in recognition of their historic status in the competition; taking advantage, the British team reached the semi-finals of the inaugural finals event with a new generation of top 30 players such as Cameron Norrie and Dan Evans, and high ranked doubles specialists such as Jamie Murray, Neal Skupski and Joe Salisbury.
