Louis Grodecki (18 July 1910, Warsaw – 28 March 1982, Paris) was a French art historian. A disciple of Henri Focillon since 1929, shortly after his arrival in France, and naturalized French in 1935, he met art historian Erwin Panofsky in 1949 at the Institute for Advanced Study in Princeton. Grodecki is famous for his work on romanesque stained glass, of Paris, Picardy and the Nord-Pas de Calais region. His most notable works are about the stained glasses of Chartres Cathedral, in particular a complete catalogue which he never finished. He was a reviewer for the doctoral dissertation of E. Wayne Craven.
