Frederic William Austin was an English baritone singer, a musical teacher and composer in the period 1905–30. He is perhaps best remembered for his arrangement of Johann Pepusch's music for a 1920 production of The Beggar's Opera by John Gay, and its sequel Polly in 1922; and for his popularization of the melody of the carol The Twelve Days of Christmas. Austin was the older brother of the composer Ernest Austin (1874–1947).
