Ernst Haeussermann (3 June 1916 – 11 June 1984) was a German-born Austrian theatre director and actor. Haeussermann was the son of the actor Reinhold Häussermann. Because of his Jewish origins, he was forced to flee Austria after the Anschluss of 1938. He settled in the United States, and appeared in small roles in several Hollywood productions. He returned to Austria after the war, and he worked in the country's most prominent theatres. He was married twice: first to Johanna Lothar, a fellow émigré he met in America and later to the actress Susi Nicoletti.
