The incident happened Tuesday and involved the USS Thunderbolt, a Cyclone-class patrol ship involved in an exercise with American and other vessels in the Gulf.
The official says the Iranian naval vessel came within 150 yards (137 meters) of the Thunderbolt.
Iranian authorities did not immediately report the incident.
The American defense official spoke on condition of anonymity as the incident had yet to be made public.
