The Battle of Melantias or Battle of Melanthius (Greek: Μάχη τής Μελαντιάδος), which took place in 559, was a battle between the armies of the Kutrigurs, commanded by Zabergan, and the Byzantine Empire, under the command of general Belisarius. Though substantially outnumbered, the Byzantine army decisively won the battle and forced the Kutrigurs to withdraw in bad order.
