Basil Apokaukos or Apokauchos (Greek: Βασίλειος Ἀπόκαυκος/Ἀπόκαυχος) was a Byzantine governor of the Peloponnese at the turn of the 11th century. Basil is chiefly mentioned in the hagiography of Saint Nikon the Metanoeite. He probably hailed from the Peloponnese and is the first recorded member of the Apokaukos family, most of whose members were active in later centuries. It is however possible, based on the comments added by Bishop to the history of John Skylitzes, that he was actually a member of the Apokapes family, and that the two families were one and the same.
