Jacques Carlu (7 April 1890 Bonnières-sur-Seine – 3 December 1976 Paris) was a French architect and designer, working mostly in Art Deco style, active in France, Canada, and in the United States.
Through the 1910s Carlu studied on site with British city planner Thomas Hayton Mawson, Pittsburgh architects Palmer and Hornbostel, and in the Paris studios of Victor Laloux.
His most famous building is likely the Palais de Chaillot, Trocadéro, near the Eiffel Tower, which was designed for the Exposition Internationale des Arts et Techniques dans la Vie Moderne (1937).
The building's long wings now serve as museum space, and it features sculptural groups on the attic by Raymond Delamarre, Carlo Sarrabezolles and Alfred Bottiau.
Among his important interiors are the 1930 Eaton Auditorium in Toronto (now known as "The Carlu"), the 1943 French Nationality Room at the University of Pittsburgh's Cathedral of Learning, and other venues.
