Scouting in Greater London is about Scouting in the official region of Greater London. It is largely represented by the Scout Association of the United Kingdom and some Groups of traditional Scouting including the Baden-Powell Scouts' Association. The Scout Association has recently defined Greater London as a Scout Region with a Regional Commissioner.
As the capital city of the United Kingdom, London has played a key role in the development of Scouting. In 1909 some troops broke away from Baden-Powell's official Boys Scouts to form the British Boy Scouts. Sir Francis Vane was the leader and previously Baden-Powell's Commissioner for London..
One of the oldest Scout Groups in London is the 1st City of London Scout Group, which is still notable as the only Scout Group in the traditional City of London.
The service performed by Scouts during war and particularly during air raids and the Blitz on London in World War II is recognised by their presence every year on Remembrance Day at the Cenotaph in London.
London Scouts celebrated the centenary of Scouting on 1 Aug 2007 in many ways, including the New Year's Day Parade in which many Explorer Scouts were led by the Enfield District Scout Band, LIVE 07, Festival of Scouting, and a Sunrise Ceremony at the London Eye. The first UK international camp of the new Scouting century was Campdowne 2008 in July 2008, where nearly 2000 participants from the UK and 23 other countries camped at Downe Scout Activity Centre.
