Charles Henri-Camille Lemaresquier (October 16, 1870, Sète - January 6, 1972, Paris) was a French architect and teacher.
Lemaresquier was born in Sète, in southern France, into a family of artists, and apprenticed to a Parisian architect at the age of 16.
In the summer and fall of 1927, Lemaresquier represented France on the jury of nine European architects judging the high-profile Palace of Nations competition, assessing the 375 entries alongside fellow judges such as Hendrik Petrus Berlage, Victor Horta, and Josef Hoffman.
The architect held seat #6 of the Architecture section of the Académie des Beaux-Arts from 1938 until his death in 1972.
Lemaresquier was also the father-in-law of French Prime Minister Michel Debré, who married the architect's daughter Anne-Marie.
