Muhammad of Ghazni (Persian: محمد غزنوی‎) (died 1041) was sultan of the Ghaznavid Empire briefly in 1030, and then later from 1040 to 1041. He ascended the throne upon the death of his father Mahmud in 1030. He was the younger of a set of twins; this circumstance resulted in civil strife. His reign lasted five months before he was overthrown by his twin Ma'sud I, after which he was blinded and imprisoned. Nine years later he was reinstated for a year before being slain by his nephew Maw'dud. According to Ferishta, his reign lasted only 50 days before he was blinded and imprisoned on the order of Ma'sud I. A year later he was executed by his nephew Maw'dud after losing a battle in Nangrahar.
