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-time, Appalachian, jug band, Hawaiian and blues) but the program 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 funds raised are donated back to local organisations that assist the jamboree, including the CFA, John Powell Reserve, Public Hall, Music Hall and Primary School. The jamboree has assisted in the purchase of a defibrillator, a sound system and acoustic insulation for the hall, shower block for the oval, improvements to the cricket pavilion and oval surrounds, and vital equipment for the CFA and school.
