Jakob Ullmann (born 12 July 1958 in Freiberg, East Germany) is a German composer and university professor.
After refusing to undergo military service in East Germany, Ullmann worked as groundskeeper, boilerman and house painter from 1978 until 1982 in Dresden.
Being denied official enrollment in Berlin's Academy of Fine Arts, he studied composition privately with Friedrich Goldmann.
His first major presentation in concert was in East Berlin in 1986, receiving positive reviews as well as a first official publishing deal for his string quartet's score in print.
