Endre Kőrös (September 18, 1927 – February 18, 2002) was a Hungarian chemist mostly known in the field of nonlinear chemical dynamics for developing the FKN mechanism, a description of the Belousov–Zhabotinsky reaction involving 11 reactions and 12 species (21 intermediate species and 18 elementary steps), in 1972 with his colleagues Richard J.

He introduced the concept of charge transfer auto-catalysis into the understanding of the spatio-temporal behavior of isotope-exchange reaction.

In the same period, he also worked on radio-chemistry and developed some techniques to purify cellulose based ion-exchange molecules.

In the following years, Endre Kőrös worked closely with various Hungarian colleagues and found several novel chemical oscillators.

In 1990 he won the Széchenyi Prize together with Miklós Orbán and Zoltán Noszticzius for their contributions to the understanding of chemical oscillatory reactions.
