Thomas Zink (born 14 April 1949 in Berlin) is a German mathematician.
He currently holds a chair for arithmetic algebraic geometry at Bielefeld University.
In 1992, he was awarded the Gottfried Wilhelm Leibniz Prize of the Deutsche Forschungsgemeinschaft joint with Christopher Deninger (Westfälische Wilhelms-Universität of Münster), Michael Rapoport (University of Wuppertal) and Peter Schneider (University of Cologne).
The four researchers succeeded to apply modern methods of algebraic geometry to the solution of diophantine equations.
Furthermore, he is a member of the German Academy of Sciences Leopoldina (Halle an der Saale).
