Eugène Auguste Nicolas Millon (24 April 1812 – 22 October 1867) was a French chemist and physician. He is remembered in the name of Millon's reagent which reacts with tyrosine in proteins to form a brown precipitate. The reagent is used for determination of the presence of soluble proteins.

Millon was born in Saint-Seine-l'Abbaye and after his education, he taught briefly at the Collège Rollin after before training in medicine at the military hospital at Val-de-Grâce from 1832 to 1835. After serving for a while in the army he left surgery to study pharmacy and chemistry and became a pharmacist in 1838, serving from 1850 to 1865 in Algeria. His most well-known contribution was the reaction of mercury and nitric acid with egg albumen which produces a white precipitate that turns red on heating. His other contributions were on compounds of chlorine and iodine including the acids. He examined salts in blood.{{cite journal|author=Wisniak, J.|year=2020|title=Auguste-Nicolas-Eugene Millon, Millon reagent, chlorine derivatives, and blood. |journal=Revista CENIC Ciencias Químicas|volume= 51|issue=2|pages=337-352| url=https://revista.cnic.cu/index.php/RevQuim/article/view/806 }}{{cite journal|title=L'œuvre scientifique d'Eugène Millon | author=Malangeau, Pierre| journal=Revue d'Histoire de la Pharmacie Année |year=1968 |pages=73-82|url= https://www.persee.fr/doc/pharm_0035-2349_1968_num_56_197_7743 |lang=fr}}{{cite book|author=Anon|url=https://iris.univ-lille.fr/handle/1908/4892|title=E.
