Ermolao Barbaro (1453/4–93) was a patrician and diplomat from Venice in the later fifteenth century. His short life meant that he enjoyed only a modest diplomatic career. His major contribution to the history of diplomacy is his short treatise, On the Office of the Diplomat (c. 1489–93), which was the first European treatment devoted to the resident ambassador, a then new development in European diplomacy.
