Husayn (also known as Soltan Hosayn) (1668?–1726) was the last powerful Safavid king of Persia. He ruled from 1694 to 1722.

During his last year of reign, Afghans revolted against his cousin, governor of Kabul. After killing him, they laid siege to Isfahan. He was not informed of the revolt by his courtiers before the siege of Isfahan.

He then had to coronate the leader of the Afghans, Mahmud, while his son, Tahmasp II continued to claim the throne. Husayn was killed several years later by Mahmud.
