The Costoboci are an ancient people located, during the Roman imperial era, between the Carpathian Mountains and the river Dniester.

The Costoboci invade the Roman empire in CE 170 or 171, pillaging its Balkan provinces as far as central Greece, until they are driven out by the Romans.

Shortly afterwards, the Costoboci's territory is invaded and occupied by Vandal Hasdingi and the Costoboci disappear from history.
