Charles Léon Stephen Sauvestre (26 December 1847 - 18 June 1919) was a French architect. He is notable for being one of the architects contributing to the design of the world-famous Eiffel Tower, built for the 1889 Universal Exposition in Paris, France.
Sauvestre was born in Bonnétable, Sarthe in First French Empire in 1847. His father Charles Sauvestre was a writer, socialist, activist and teacher and his mother was a housewife. He graduated with first class honors from École Spéciale d'Architecture in 1868. He died in 1919.
Sauvestre contributed to the design of the Eiffel Tower, adding the decorative arches to the base, a glass pavilion to the first level and the cupola at the top. He also chose the color of the tower. He received the support of Gustave Eiffel who bought the rights to the patent on the design which he had filed together with Maurice Koechlin and Émile Nouguier. He was also the head of Architecture department of Compagnie des Etablissements Eiffel
