Rudolf "Rudi" Noack (30 March 1913 - c. 30 June 1947) was a German footballer. A forward, he played in the 1934 FIFA World Cup, scoring one goal in the tournament against Czechoslovakia in the semi-finals.
During World War II Noack was called up and served as a corporal in the German Army with anti-aircraft units stationed mainly in Hamburg, Vienna and in Bohemia (Czechoslovakia) where at the end of the war he was captured by Soviet forces. He died in a prisoner of war camp at Rakitianka near Orsk, Russia, on 30 June 1947.[2]
