Sayyid Muhammad Jaunpuri (Urdu: سید محمد جونپورى; 9 September 1443 – 23 April 1505) was an Indian religious leader and the founder of the Mahdavia movement.

He claimed to have been divinely appointed as the promised Mahdī, in fulfillment of the Islamic prophecies regarding the end times.

Hailing from Jaunpur, he traveled extensively throughout India, Arabia and Khorasan.

By the age of 53 he embarked on the Hajj pilgrimage to Mecca, where in 1496 (901 Hijri), after circumambulating the Kaaba, he declared that he was the Promised Mahdi and whoever believes in him is a Momin.

After staying in Mecca for nearly seven or nine months,[2] he returned to India where he proclaimed himself Mahdi at Ahmedabad and later at Badhli (near Patan, Gujarat).
