Shams ud-Din Kayumars (Persian: شمس الدین کیومرث; c. 1285 – 13 June 1290) was the eleventh sultan of Delhi, and a son of Muiz ud-Din Qaiqabad (a grandson of Balban).

His father Muiz ud din Qaiqabad was murdered by a Khalji noble, Jalal ud-Din Firuz Khalji, during the Khalji Revolution.

Jalal ud-Din assumed the throne after murdering Kayumars, ending the Mamluk dynasty and starting the Khalji dynasty.

[1] By that time Qaiqabad was struck down with paralysis and the Turkic nobles had raised his three-year-old son Kayumars to the throne as the Sultan.
