Luigi Rossi (fl. c. 1819 - 1821), not to be confused with the earlier composer or later painter, parliamentarian, or filmmaker of the same name, was an Italian cartographer and scholar best known for his 1820 Nuovo Atlante di Geografia universale. He also translated into Italian the epic poem Posthomerica by the Greek poet Quintus Smyrnaeus. Despite his noble title as 'Cavaliere,' he does not appear to be the same person as his contemporary, Count Pellegrino Luigi Rossi, who was an economist and high-level government official in France and the Papal States.
