Anselme Payen (January 6, 1795 - May 12, 1871) was a French chemist. He was born in Paris, where he studied at the École Polytechnique. At the age of 20 he became manager of a borax-refining factory, where he developed a process for synthesizing borax from soda and boric acid. He also invented new processes for refining sugar, a decolorimeter, a way to refine starch and alcohol from potatoes, and a method for determination of nitrogen.

Payen became especially famous for the discovery of the first enzyme, diastase; also for his works on cellulose.
