The County of Apulia and Calabria (Latin: Comitatus Apuliae et Calabriae), later the Duchy of Apulia and Calabria (Latin: Ducatus Apuliae et Calabriae), was a Norman state founded by William of Hauteville in 1043, composed of the territories of Gargano, Capitanata, Apulia, Vulture, and most of Campania. It became a duchy when Robert Guiscard was raised to the rank of duke by Pope Nicholas II in 1059.

The duchy was disestablished in 1130, when the last duke of Apulia and Calabria, Roger II, became King of Sicily. The title of duke was thereafter used intermittently as a title for the heir apparent to the Kingdom of Sicily.
