Hannes Hegen (real name Johannes Eduard Hegenbarth, born 16 May 1925 in Böhmisch Kamnitz, now Česká Kamenice- – 9 November 2014 in Berlin) was a German illustrator and caricaturist and is most famous for creating the East German comic book Mosaik and its original protagonists, the Digedags.

He studied at the University of Applied Arts Vienna and at the Academy of Visual Arts Leipzig. After his studies, he worked in Berlin, illustrating several magazines.

His own creation Mosaik was first published in December 1955. Hegen was solely responsible for only the first issues of the book. Later a team of artists and writers worked on the book, but only Hegen was credited on the cover. 223 issues were produced. Hegen worked on Mosaik until 1975, when he had a disagreement with the publisher and quit working, taking the rights to the Digedags characters with him. The Mosaik team continued without him and created new characters to appear in Mosaik.

Today, Hegen lives in Berlin and is working on reprint and book editions for the original Mosaik comics.

In 2008 Hannes Hegen received the Max & Moritz Prize, the most important German prize for comic artists from the International Comic Salon Erlangen. In 2010 he was awarded for his creative work, the Order of Merit of the Federal Republic of Germany (Knight's Cross, or Merit Cross on Ribbon, German: Verdienstkreuz am Bande).
