Shigefumi Mori (森 重文 Mori Shigefumi, born February 23,1951) is a Japanese mathematician, known for his work in algebraic geometry, particularly in relation to the classification of three-folds.

He generalized the classical approach to the classification of algebraic surfaces to the classification of algebraic three-folds. The classical approach used the concept of minimal models of algebraic surfaces. He found that the concept of minimal models can be applied to three-folds as well if we allow some singularities on them.

The extension of Mori’s results to dimensions higher than three is called the Mori program and as of 2005, is an extremely active area of algebraic geometry.

He was awarded the Fields Medal in 1990 at the International Congress of Mathematicians.
