Bacchides () was a Hellenistic Greek general; friend of the Syrian-Greek king Demetrius; and "ruler in the country beyond the river"—Euphrates. Demetrius sent him in 161 BCE to Judea with a large army, in order to invest the recreant Alcimus with the office of high priest (I Macc. vii. 8, 9). The peaceable Assideans credulously expected friendship from him; but, contrary to oath and covenant, he cruelly slew sixty of them (ib. vii. 16). Leaving Jerusalem, he made a slaughter-house of Bezeth (Bethzecha), and after handing the country over to Alcimus, returned to the king (ib. vii. 19, 20).
