Pierre Francastel (8 June 1900 – 2 January 1970) was a French art historian, best known for his use of sociological method.
Francastel's initial period of study was in literature, at the Sorbonne.
He worked in building conservation at Versailles while undertaking research toward his doctoral degree, which was on the sculpture of Versailles, and in 1928 he published a monograph, including a critical catalogue, on the seventeenth-century French sculptor François Girardon.
In 1930, he was appointed director of the Warsaw Institut français, and in 1936 he was appointed professor at the University in Strasbourg.
Francastel is also noted for his promotion of spatial concerns, both physical and conceptual, prefiguring the "spatial turn" of later scholars such as Henri Lefebvre.
