Lucos Cozza (born in Rome, Italy, on 11 April 1921 – 27 June 2011) was a Roman archaeologist.
Born in Rome, Cozza was the son of the sculptor, count Lorenzo Cozza (Orvieto 1877 - Roma 1965), and the grandson of archaeologist Adolfo Cozza (Orvieto 1848 - Roma 1910).
Cozza was a student of Giuseppe Lugli, the author of many scholarly books about Italian prehistory and the topography of Rome; his best-known work is on the Temple of Hadrian. He also wrote an archeological guide book to Roman antiquities, translated into several languages.
In 1957 he began the excavation, along with Ferdinando Castagnoli, of the Latin federal sanctuary at Lavinium.
