Johann Baptist Gänsbacher (8 May 1778 in Sterzing – 13 July 1844 in Vienna), Austrian musical composer, was born in 1778 in Sterzing in the County of Tyrol. His father, a schoolmaster and teacher of music, undertook his son's early education, which the boy continued under various masters until 1802, when he became the pupil of the celebrated Abbé G. J. Vogler. In 1823-24, he was one of the 50 composers who composed a variation on a waltz by Anton Diabelli for Vaterländischer Künstlerverein.
