Nasir al-Din Mahmud I (1088–1094) was an infant sultan of the Seljuk Empire from 1092 to 1094, with most power held by his mother Terken Khatun. He was a younger son of the former sultan Malik Shah I and proclaimed sultan at Baghdad by the caliph al-Muqtadi. Under his notional reign, the empire built by his father and Alp Arslan fragmented. After Mahmud's forces lost a battle at Borujerd, he and his mother were assassinated by the family of the former vizir Nizam al-Mulk.
