Henri Eugène Padé (French: [pade]; 17 December 1863 – 9 July 1953) was a French mathematician, who is now remembered mainly for his development of Padé approximation techniques for functions using rational functions.

Padé studied at École Normale Supérieure in Paris.

In 1890 Padé returned to France, where he taught in Lille while preparing his doctorate under Charles Hermite.

He then became an assistant professor at Université Lille Nord de France, where he succeeded Émile Borel as a professor of rational mechanics at École Centrale de Lille.

Padé taught at Lille until 1902, when he moved to Université de Poitiers.
