Cniva (also given as Kniva, reign circa 250 to possibly 270) was the king of the Goths who defeated Emperor Decius (reign 249-251) at the Battle of Abritus in 251. Little is known of him other than his campaign in 251, in which he successfully took Philipopolis, killing over 100,000 Roman citizens and enslaving survivors, laid siege to the city of Nicopolis, and defeated the Romans under Decius, killing both the emperor and his son.
