John Fante (April 8, 1909 – May 8, 1983) was an American novelist, short story writer, and screenwriter. He is best known for his semi-autobiographical novel Ask the Dust (1939) about the life of Arturo Bandini, a struggling writer in Depression-era Los Angeles. It is widely considered the great Los Angeles novel, and is one in a series of four, published between 1938 and 1985, that are now collectively called "The Bandini Quartet". Ask the Dust was adapted into a 2006 film starring Colin Farrell and Salma Hayek. Fante's published works while he lived included five novels, one novella, and a short story collection. Additional works, including two novels, two novellas, and two short story collections, were published posthumously. His screenwriting credits include, most notably, Full of Life (1956, based on his 1952 novel by that name), Jeanne Eagels (1957), and the 1962 films Walk on the Wild Side and The Reluctant Saint.

Fante's early years were spent in relative poverty. The son of an Italian born father, Nicola Fante, and an Italian-American mother, Mary Capolungo, Fante was educated in various Catholic schools in Boulder and Denver, Colorado, and briefly attended the University of Colorado. In 1929, he dropped out of college and moved to Southern California to concentrate on his writing. He lived and worked in Wilmington, Long Beach, and in the Bunker Hill district of downtown Los Angeles, California. He is known to be one of the first writers to portray the tough times faced by many writers in L.A. His work and style has influenced such similar authors as "Poet Laureate of Skid Row" Charles Bukowski and influential beat generation writer Jack Kerouac.
