Gian Maria Tosatti (Rome, 1980) is an Italian visual artist, journalist and essayist.

He trained artistically between Pontedera, Warsaw and Rome in the territory of performance. He lived in New York between 2009 and 2018. He currently lives in Naples. His projects are long investigations of precise topics related to the concept of identity, from political and spiritual perspectives. His work consists mainly of large site-specific installations, conceived for entire buildings or urban areas. His practice often involves the communities of the places for which the works are developed.

In 2014 Domus mentions his work My dreams, they'll never surrender (permanent intervention at Castel Sant'Elmo in Naples) among the world's top 10 exhibitions for that year. In 2015, the international magazine ArtReview listed him among the world's 30 most interesting artists of his generation (Future Greats). He worked for a year in the Calais Jungle making environmental interventions that are currently the only visible evidence of that city's existence.

Since 2021 he has been artistic director of the Quadriennale di Roma.
In 2022 he is the only artist in the Italian Pavilion at the 59th Venice Biennale.
