Oliver Hazard Perry La Farge (19 December 1901 - 2 August 1963) was an American writer and anthropologist, perhaps best known for his 1930 Pulitzer Prize-winning novel Laughing Boy. Named for his uncle, Oliver H.P. Lafarge, he is the grandson of the artist and stained-glass pioneer John La Farge, nephew of the noted Beaux-Arts architect Christopher LaFarge and the father of the folk singer and painter Peter La Farge.
La Farge's short stories were published in The New Yorker and Esquire magazines. His more notable works, fiction and non-fiction, focus on Native American culture.
La Farge, a Newport, Rhode Island New Englander whose grandfather was of French descent and whose other ancestors included English colonists and Narragansetts, was an anthropologist who discovered two previously unknown languages while on scientific expeditions to Central America and the American Southwest. He is well-known for his pioneering visit, with Frans Blom in 1925, to Mexico and what has since become known as the Olmec heartland, (re)discovering San Martin Pajapan Monument 1 and, most importantly, the ruins of La Venta, one of the major Olmec centers.
La Farge also spent much of his adult life championing Indian rights and was president of the Association on American Indian Affairs for several years.
His published output included several scientific papers and non-fiction books, as well as several novels and a column for the Santa Fe newspaper The New Mexican, some of which were released in book form as The Man With the Calabash Pipe.
La Farge had two children by his first wife, heiress Wanden Matthews: a son, Oliver Albee La Farge, and a daughter, Povy; and another son, John Pendaries "Pen" La Farge, by his second wife, Consuelo Baca La Farge. His 1956 book Behind the Mountains is based on the reminiscences of Consuelo's family, who were ranchers in northern New Mexico. After La Farge and Matthews divorced in 1935, Oliver Albee changed his name to Peter La Farge and became a Greenwich Village folksinger with five Folkways Records albums.
La Farge died in Santa Fe, New Mexico, in 1963.
