Mauro Fornari (fl. 1730 - 1797) was an Italian monk and cartographer. He was a member of the Olivetan order, and appears to have lived and worked in Milan. His only printed cartographic works are a set of six maps of the state of Milan (Como, Cremona, Lodi, Milano, Pavia and Varese) engraved by Domenico Cagnini. The individual maps appear to be quite scarce, only appearing in a few institutional collections. The full set seems only to be held in the Herzogin Anna Amalia Bibliothek Klassik DEHAA. A further work attributed to Fornari, though not apparently published, is recorded in the Convento di S. Marco: a 6-sheet Pianta di Milano.
