Paul Bigot (20 October 1870 – 8 June 1942) was a French architect.
Bigot was born in Orbec, Calvados. He studied architecture at the École nationale supérieure des Beaux-Arts in Paris, in the atelier of Louis-Jules André. He won the Grand Prix de Rome in 1900, which enabled him to study in Rome at the Villa Medici. He later became a professor at the École des Beaux-Arts.
He is particularly known for Le Plan de Rome, a large architectural model of Ancient Rome. It is a plaster model of about 70 square metres at a scale of 1:400, showing Rome as it would have been in the time of the emperor Constantine I (4th century AD). The model is preserved at the University of Caen and is itself listed as an ancient monument. A second version is in the Royal Museums of Art and History in Brussels.
Bigot was also the architect of the Institut d'art et d'archéologie, in Paris, completed in 1928.
