The House of Tocco (pl. Tocchi, Ancient Greek: Τόκκος, romanized: Tókkos pl. Τόκκοι, Tokkoi) was an Italian noble family from Benevento that came to prominence in the late 14th and 15th centuries, when they ruled various territories in western Greece as Counts Palatine of Cephalonia and Zakynthos and Despots of Epirus. During their brief period of rule in Greece, they were one of the most ambitious and able Latin dynasties in the region, and were one of the few to leave descendants lasting nearly until modern times, in which they claimed to represent the senior matrilineal heirs of the Palaiologos dynasty.
The earliest known members of the family are recorded in the 12th century, in Benevento, though Tocco family genealogies claimed that they originated much earlier, with forged connections to ancient Gothic kings Theodoric the Great and Totila, as well as to the ancient Epirote king Pyrrhus. Members of the family held various prominent offices during the rule of the Hohenstaufen and Angevin dynasties in the Kingdom of Sicily. As a result of the family's loyalty to the Angevin princes in Greece, such as the titular Latin emperors Philip I of Taranto and Robert of Taranto, Leonardo I Tocco was rewarded c. 1357 with the grant of the County Palatine of Cephalonia and Zakynthos, islands off the western coast of Greece.
