Francis Carco (born François Carcopino-Tusoli) (3 July 1886 – 26 May 1958) was a French author, born at Nouméa, New Caledonia. He was a poet, belonging to the Fantaisiste school, a novelist, a dramatist, and art critic for L'Homme libre and Gil Blas. During World War I he became an aviation pilot at Étampes, after studying at the aviation school there. His works are picturesque, painting as they do the street life of Montmartre, and often being written in the argot of Paris. He has been called the "romancier des apaches." His memoir, The Last Bohemia: From Montmartre to the Latin Quarter, contains reminiscences of bohemian life in Paris during the early years of the 20th century.

He had an affair with the short story writer Katherine Mansfield in February 1915. The narrator Raoul Duquette of her story Je ne parle pas français (who has a cynical attitude to love and sex) is partly based on him, and her story An Indiscreet Journey is based on her journey through the war zone to spend four nights with Corporal Francis Carco near Gray. She saved as a memento of him a fake letter from "Julie Boiffard" asking her to visit (which is now held in the Turnbull Library). She also wrote a letter to her husband from Carco's Paris flat on 8/9 May 1915.

Carco held the ninth seat at Académie Goncourt from 1937 to 1958. He is buried in the Cimetière de Bagneux. He was the author of:
