Peter Kolosimo, pseudonym of Pier Domenico Colosimo (15 December 1922 - 23 March 1984), was an Italian journalist and writer. Together with the later Erich von Däniken, he is ranked amongst the founders of pseudoarchaeology (in Italian: fantarcheologia), a controversial topic which aims to study the origins of ancient civilizations using theories and methods not accepted by the scientific community. He also popularised ancient astronauts theories of contact between extraterrestrial beings and ancient human civilizations.
Born in Modena, he lived in Bolzano for much of his life. In 1969 he won the Premio Bancarella, one of Italy's most prestigious literary prizes, for Non è terrestre ("Not from Earth"). His books were translated in 60 countries, including Russia, Japan and China.
Despite his highly controversial theories, he has been coordinator of the Italian Association of Prehistorical Studies.
Kolosimo died in Milan in 1984.
