Tuscan (Italian: toscano [djaˈlɛtto tosˈkaːno; di.a-]; locally: vernacolo) is a set of Italo-Dalmatian varieties of Romance spoken in Tuscany, Corsica, and Sardinia.

Tuscan, especially its Florentine variety, formed the basis for establishing Standard Italian. Due mostly to the prestige of the works by Dante Alighieri, Petrarch, Giovanni Boccaccio, Niccolò Machiavelli, and Francesco Guicciardini, the Tuscan-derived elaboration became the primary language of culture throughout Italy, and later the official language of all of the historic Italian states and then of the Kingdom of Italy when it was formed.
