Mikhail (Misha) Lyubich (born 25 February 1959 in Kharkiv, Ukraine) is a mathematician who has made important contributions to the fields of holomorphic dynamics and chaos theory.

From 2002-2008, he also held a position of Canada Research Chair at the University of Toronto.

He is credited with several important contributions to the study of dynamical systems.

In his 1984 Ph.D. thesis, he proved fundamental results on ergodic theory and the structural stability of rational mapping.

[2] In 1999, he published the first non-numerical proof of the universality of the Feigenbaum constants in chaos theory.
