Tommaso Fiore (7 March 1884 – 4 June 1973) was an Italian Meridionalist writer and a socialist intellectual and politician.
He is known for his attention and his descriptions and studies on the inhumane conditions of South Italy's and Apulian peasants at that time.
He's also known for his Viareggio Prize-winning book Un popolo di formiche ("A people of ants").
In the 1920s, he was appointed as mayor (Italian: sindaco) of his hometown Altamura.
During the twenty-year period of Italy's fascist era, he strenuously opposed the regime before being sent into internal exile in 1942 and then being jailed in 1943.
