Giovanni Petroschi (1715 - 1766) was an Italian engraver, cartographer, and map publisher based in Rome. He was considered the foremost authority on Latin American cartography in the first half of the 18th century. He published several important Jesuit maps, including Carolo Brentano's Provincia Quitensis (1751) and Jose Antonio de Sylverio Villaseñor y Sánchez 's map of Mexico (1754). Although significant as a cartographer, Petroschi, like many Jesuit publishers, lived humbly in religious obscurity.
