The County of Apulia and Calabria, later the Duchy of Apulia and Calabria, was a Norman country founded by William of Hauteville in 1042 in the territories of Gargano, Capitanata, Apulia, Campania, and Vulture. 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 of Sicily became King of Sicily. The title of duke was thereafter used intermittently as a title for the heir apparent to the Kingdom of Sicily.

Drogo of Hauteville was made "count" of Apulia & Calabria by Emperor Henry III, with territories lost by Guaimario IV of the Principality of Salerno

Indeed William I of Hauteville, who returned in September 1042 in Melfi, was recognized by all the Normans as supreme leader. He turned to Guaimar IV, Lombard, Prince of Salerno, and Rainulf Drengot, Count of Aversa, and offered both an alliance. With the unification of the two Norman families, Altavilla and Drengot, Guaimar offered official recognition of the conquests and at the end of the year, an assembly of Lombards and Norman barons at Melfi met with Rainulf and William, which ended at the beginning of the following year (1043).
