The Guildford Banjo Jamboree is a gathering of musicians and music lovers in the small country town of Guildford, in Central Victoria, Australia. It was conceived in 2004 to showcase the banjo in its many forms and related styles. The emphasis has been on American string band music (Bluegrass, Old-timey, Appalachian, Jugband, Hawaiian and Blues) but the programme also encompasses other styles such as Celtic, Klezmer, Jazz and contemporary music.
The Jamboree owes much of its success to local residents, businesses and organisations. Each year the funds raised are donated back to local organisations which assist the Jamboree, such as the CFA, the John Powell Reserve, the Public Hall, the Music Hall, and the Primary School. The Jamboree has assisted in, among other things, the purchase of a defibrillator, a sound system and acoustic insulation for the hall, the shower block for the oval, improvements to the cricket pavilion and the oval surrounds, and vital equipment for the CFA and the School.
