Auguste Perret (12 February 1874 - 25 February 1954) was a French architect and a world leader and specialist in reinforced concrete construction. In 2005 his post-WWII reconstruction of Le Havre was declared by UNESCO one of the World Heritage Sites.

He was born in Ixelles, Belgium. He was the brother of the architect Gustave Perret. He worked on a new interpretation of the neo-classical style. He continued to carry the banner of nineteenth century rationalism after Viollet-le-Duc. His efforts to utilize historical typologies executed in new materials were largely eclipsed by the younger media-savvy architect Le Corbusier, Perret's one-time employee, and his ilk. From 1940 Perret taught at the Ecole des Beaux-Arts. He won the Royal Gold Medal in 1948 and the AIA Gold Medal in 1952.
