The Calvana is a cattle breed from Tuscany, in central Italy. It is particularly associated with the Calvana region in the provinces of Florence and Prato, but is also raised in the provinces of Pistoia and Siena. It was previously considered a type within the Chianina breed, but is now recognised as a separate breed. A herdbook was opened in 1985. It is one of the 16 minor Italian cattle breeds of limited diffusion recognised and protected by the Ministero delle Politiche Agricole Alimentari e Forestali, the Italian ministry of agriculture.
