The World Association of Theoretical and Computational Chemists (WATOC) aims to promote the field of theoretical and computational chemistry and to advance the interactions between scientists working in this field worldwide.

WATOC holds triennial Congresses to promote scientific exchange.
The next Congress will be in Vancouver, Canada (16-21 August 2020).

WATOC awards two types of medals to honor outstanding theoretical and computational chemists: the Schrödinger medal to senior scientists, and the Dirac medal to scientists under the age of 40.
