Michael Umlauf (August 9, 1781 – June 20, 1842), was an Austrian composer, conductor, and violinist.
His earliest known compositions were a series of ballet scores for the court theatres dated 1804.
Umlauf retired in 1825 during Barbaia’s direction of the court opera, and applied without success for the post of second Kapellmeister at the Stephansdom.
It was 1840 before he again came to the fore, this time as music director at the two court theatres, but his lengthy absence had left him quite out of touch and he soon retired again, dying at Baden bei Wien not long after.
Umlauf's name is most familiar from his connections with Ludwig van Beethoven, whose works he conducted on numerous occasions.
