Christian Ernst Stahl (21 June 1848 – 3 December 1919) was a Franco-German botanist from Schiltigheim, Alsace. He worked on the ecophysiology of plants and has been considered a pioneer of chemical ecology in his work examining the defences of plants against herbivores, although he considered snails and slugs to be the dominant herbivores that drove plant evolution rather than insects.
