(Βουβάρης), the son of Megabazus, a Persian, was sent into Macedonia to make inquiries after the missing Persian envoys, whom Alexander, the son of Amyntas I., had caused to be murdered at his father's court, about B. C. 507. Alexander induced Bubares to pass the matter over in silence, by giving him great presents and also his sister Gygaea in marriage. By this Gygaea Bubares had a son, who was called Amyntas after his grandfather. (Hdt. 5.21, 8.136.)

In conjunction with Artachaees, Bubares superintended the construction of the canal which Xerxes made across the isthmus of Athos. (Hdt. 7.22.)
