Ulrich Wildgruber (born November 18, 1937 in Bielefeld, † November 30, 1999 on Sylt) was a German actor.

The son of a bookbinding master from Bielefeld was inspired to become an actor since his schooldays and working in an amateur theater. He began his acting training in several stations with private acting teachers, which was interrupted again and again, and he had to fight through life with numerous jobs, but without losing sight of his goal. It was not until 1960 that he was accepted to study acting at the Max Reinhardt Seminar in Vienna, but he left because of controversy. He made his debut in 1963 at the Vienna Volkstheater in Bertolt Brecht's mother Courage and her children under the direction of Gustav Manker as Schweizererkas in a performance that broke the Brecht boycott in Austria.
