Stefano Bardini (1836–1922) was an Italian connoisseur and art dealer in Florence who specialized in Italian paintings, Renaissance sculpture, cassoni and other Renaissance and Cinquecento furnishings and architectural fragments that came on the market during the urban regeneration of Florence in the 1860s and 70s. Trained as a painter and expert copyist at the Accademia di Belle Arti Firenze from 1854, Bardini received increasing commissions as a restorer and expanded into selling works of art from 1870 onwards.
