Christopher Deninger (born 8 April 1958) is a German mathematician at the University of Münster.
Deninger obtained his doctorate from the University of Cologne in 1982, under the supervision of Curt Meyer.
In 1992 he shared a Gottfried Wilhelm Leibniz Prize with Michael Rapoport, Peter Schneider and Thomas Zink.
In 1998 he was a plenary speaker at the International Congress of Mathematicians in 1998 in Berlin.
In 2012 he became a fellow of the American Mathematical Society.Deninger has worked on a broad range of mathematical topics.
While focussing on arithmetic geometry, including his particularly influential work on L-functions, Deninger has also studied analytical questions, often with an eye on analogies between arithmetic and analysis.
