Helmut Degen (born 14 January 1911 in Aglasterhausen – died 2 October 1995 in Trossingen) was a German composer.
Degen studied composition with Wilhelm Maler and Philipp Jarnach; and score and instrumentation with Ernst Gernot Klussmann at the Rheinische Musikschule in Cologne and the University of Bonn, writing his dissertation on Baroque librettist Friedrich Christian Bressand. He later taught theory at the Duisburg Conservatory and later at the Hochschule für Musikerziehung in Trossingen, becoming a professor in 1954.
His works include educational chamber music in modern style. His style resembles Hindemith and uses methods similar to 12-tone composition.
