ventidius cumanus ("fl." 1st century ad) was the roman procurator of iudaea province from ad 48 to c. ad 52. a disagreement between the surviving sources, the jewish historian josephus and the roman tacitus, makes it unclear whether his authority was over some or all of the province. cumanus' time in office was marked by disputes between his troops and the jewish population. ventidius cumanus failed to respond to an anti-jewish murder in samaritan territory which led to the violent conflict between jews and samaritans. following an investigation by the governor of syria, gaius ummidius durmius quadratus, cumanus was sent to rome for a hearing before the emperor claudius, who held him responsible for the violence and sentenced him to exile.
