Eduard Buchner (20 May 1860–13 August 1917) was a German chemist and zymologist, awarded with the 1907 Nobel Prize in Chemistry thanks to his work on fermentation.

Buchner was born in Munich to a physician and Doctor Extraordinary of Forensic Medicine.
In 1884, he began studies of chemistry with Adolf von Baeyer and of botany with Professor C. von Naegeli, at the Botanic Institute in Munich.
After a period working with Otto Fischer in Erlangen, Buchner was awarded a doctorate from the University of Munich in 1888.
He was wounded on August 3, 1917 and died of these wounds nine days later in Munich at age 57.
Though it is believed by some that the Büchner flask and the Büchner funnel are named for him, they are actually named for the industrial chemist Ernst Büchner.
