Qutb ad-Din Muhammad (Persian: قطب الدين Ù…Øمد; full name: Qutb ad-Dunya wa ad-Din Abul-Fath Muhammad Arslantegin ibn Anushtegin) was the first Shah of Khwarezm from 1097 to 1127. He was the son of Anushtegin Gharchai.
In around 1097, Qutb al-Din Muhammad was appointed governor of Khwarazm by the Seljuk Sultan Berkyaruk's military commander, Habashi ibn Altun-Taq. Habashi had just put down a revolt by two Seljuk amirs, Qodun and Yaruq-Tash, who had killed the previous governor of Khwarazm, Ekinchi, and wanted to rule the province themselves. Qutb al-Din Muhammad therefore took control of Khwarazm and stopped an attempt by Ekinchi's son, Toghril-Tegin, to seize the region.
