In Full Swing is a twenty piece jazz orchestra made up of players drawn from the Belconnen Musicians, a local music community organisation based in Canberra in the Australian Capital Territory.

Originally formed in 1991 by Martin Flanagan, the group has an extensive library of original music from the big band era of the 1930s and 1940s. There is a particular focus in the repertoire on standards that were performed by the Glenn Miller, Duke Ellington and Benny Goodman orchestras.
