Ferdinand IV (September 8, 1633 - July 9, 1654) was King of the Romans, of Hungary, and of Bohemia.

He was born in Vienna, the eldest son of Ferdinand III, Holy Roman Emperor and his first wife Maria Ana of Spain. His maternal grandparents were Philip III of Spain and Margaret of Austria.

He was an older brother of Mariana of Austria and Leopold I, Holy Roman Emperor.

He was made King of Bohemia in 1646, King of Hungary in 1647, and was elected King of the Romans (future ruler of the Holy Roman Empire) on May 31, 1653, and crowned at Ratisbon (Regensburg) on June 18 of the same year. He died in Vienna, predeceasing his father, leaving his younger brother, the future Leopold I, Holy Roman Emperor, as heir.
