Ala ud din Masud (fl. 1242–46) was the seventh sultan of the Mamluk dynasty (Slave dynasty).
He was the son of Rukn ud din Firuz (1236), grandson of Shah Turkan and the nephew of Razia Sultan (1236–40). After his predecessor, Muiz ud din Bahram, was murdered by the army in 1242 after years of disorder, the chiefs chose for him to become the next ruler. However, he was more of a puppet for the chiefs and did not actually have much power or influence in the government. Instead, he became infamous for his fondness for entertainment and wine. Like his predecessor, he was considered "incompetent and worthless." By 1246, the chiefs became upset with his increasing hunger for more power in the government, and replaced him with Nasir ud din Mahmud (1246–66), grandson of Iltutmish and son of Rukn-ud-din Firoz. The Mongols plundered Lahore in 1246.
