Shahbanu (in Persian: شهبانو) means Empress in Persian. It was a title that was only conferred on the third wife of Muhammad Reza Shah, Farah Diba in 1967. She was the first Empress to be crowned in Iran, excluding the two Sassanian empresses Purandokht and Azarmidokht circa 630 A.D. Previous wives of Iranian Emperors were known as Malika or Queen.
