The Showmen's Guild of Great Britain exists to protect the interests of travelling showmen in Great Britain.
The Showmen's Guild was founded as the United Kingdom Van Dwellers Protection Association in 1889 in Salford. In 1917, the Showmen's Guild of Great Britain, as it became known, was recognised as the trade association for the travelling funfair business. It acquired the right to represent the business at local and national levels.
The Guild has a code of rules and also makes representations concerning proposed legislation when appropriate. It has a membership of around 4,700 people and is organized into ten regional sections. It supports the National Fairground Archive, set up in 1994 at the University of Sheffield. The Showmen's Guild organizes fairs, such as St Giles' Fair in Oxford, co-organized with the Oxford City Council.
