Oliver Hazard Perry La Farge II (December 19, 1901 – August 2, 1963) was an American writer and anthropologist.

In addition to more than 15 scholarly works, mostly about Native Americans, he wrote several novels, including the Pulitzer Prize-winning Laughing Boy (1929).

He (re)discovered San Martin Pajapan Monument 1 and more importantly the ruins of La Venta, one of the major Olmec centers.

[1] La Farge devoted considerable study to Native American peoples and issues, especially after moving to Santa Fe, New Mexico in 1933.

[2] During World War II, La Farge served with the U.S. Air Transport Command, ending service with the rank of major.

Some of his more successful songs have Native American themes, including "As Long as the Grass Shall Grow", which takes its name from the title of one of his father's books.
