'''Ernest Vessiot''' ({{IPA|fr|vesjo|lang}}; 8 March 1865 – 17 October 1952) was a [[French people|French]] [[mathematician]]. He was born in [[Marseille]], [[France]], and died in [[La Bauche]], [[Savoie]], France. He entered the [[École Normale Supérieure]] in 1884.

He was Maître de Conférences at [[Lille University of Science and Technology]] in 1892-1893, then moved at Toulouse and Lyon.

After 1910, he was a professor of [[analytical mechanics]] and [[celestial mechanics]] at the [[University of Paris]]. He presided over entrance examinations at the [[École Polytechnique]]. As director of [[École Normale Supérieure]]  until 1935, 
he overviewed the construction of its new physics, chemistry and geology buildings of 24, Rue Lhomond.

He was elected a member of the [[Académie des Sciences]] in 1943.

Vessiot's work on [[Picard–Vessiot theory]] dealt with the integrability of [[ordinary differential equations]].
