The Neustadt International Prize for Literature is a biennial award for literature sponsored by the University of Oklahoma and its international literary publication, World Literature Today.

Giuseppe Ungaretti was an Italian modernist poet, journalist, essayist, critic, academic, and recipient of the inaugural 1970 Neustadt International Prize for Literature. A leading representative of the experimental trend known as Ermetismo ("Hermeticism"), he was one of the most prominent contributors to 20th century Italian literature. Influenced by symbolism, he was briefly aligned with futurism. Like many futurists, he took an irredentist position during World War I. Ungaretti debuted as a poet while fighting in the trenches, publishing one of his best-known pieces, L'allegria.
