The Costoboci (/ˌkɒstəˈbs/; Latin: Costoboci, Costobocae, Castabocae, Coisstoboci, Ancient Greek: Κοστωβῶκοι, Κοστουβῶκοι, Κοιστοβῶκοι[1] or Κιστοβῶκοι[2]) were a Dacian tribe located, during the Roman imperial era, between the Carpathian Mountains and the river Dniester. During the Marcomannic Wars the Costoboci invaded the Roman empire in AD 170 or 171, pillaging its Balkan provinces as far as Central Greece, until they were driven out by the Romans. Shortly afterwards, the Costoboci's territory was invaded and occupied by Vandal Hasdingi and the Costoboci disappeared from surviving historical sources, except for a mention by the late Roman Ammianus Marcellinus, writing around AD 400.
