Wolfgang Wilmanns (born 20.05.1929 in Bethel near Bielefeld in North Rhine Westphalia; died 24.12.2003 in Munich) was a German physician and university professor.    

From 1955 to 1956 he worked in Passaic, New Jersey (USA). Following a practical year he was a scholarship holder from 1958 to 1960 of the Deutsche Forschungsgemeinschaft am Institut von Feodor Lynen at the University of Munich, where he particularly focussed on bio-chemical research. His research on purine and pyrimidine synthesis led to treatment methods for leukaemia, which formed the focus of Wilmanns' research career.

Further stages of his scientific career were at the University of Marburg (Assistant Doctor to Hans Erhard Bock), whom he followed to the University of Tübingen in 1962. He became a professor there in 1971.

From 1977 to 1998 he was Director of the Medizinische Klinik III im Klinikum der Universität München in Großhadern, where he was also Director of the Institut für Klinische Hämatologie im Forschungszentrum für Umwelt und Gesundheit (GSF). He was awarded a number of outstanding prizes for research results in haematology.

In 1998 he founded the Wolfgang Wilmanns Foundation to support leukaemia and tumour research at the universities in Munich as well as the TZM. The foundation awards prizes to young scientists or groups of researchers.
