Pierre Frédéric Magnier (February 22, 1869 – October 15, 1959) was a French actor who began on the stage in the 1890s and became a prominent silent film actor in France. He was the second actor to portray Cyrano de Bergerac in any film in 1925. He continued acting until the 1950s. He is most remembered for the role of the General in Jean Renoir's La règle du jeu, where he has one of the films more poignant quotes (and the film's final line) when he praises Marcel Dalio's character as one of "a vanishing breed."
