Mir Sayyid Ali Hamadani (Persian: میر سید علی همدانی; c. 1312–1385 CE) was a Sufi sunni Muslim saint of the Kubrawiya order, who played an important role in spread of Islam in the Kashmir Valley of northern India.

[3][4] Hamadani spent his early years under the tutelage of Ala ad-Daula Simnani, a famous Kubrawiya saint from Semnan, Iran.

Sayyid Ali Hamadani travelled widely and preached Islam in Afghanistan, Uzbekistan, China, Syria, Kashmir and Turkestan.

Shib ad-Din became a follower of Mir Syed Hasan Semnani and so Hamadani was welcomed in Kashmir by the king and his heir apparent Qutbu'd-Din Shah.

Hamadani died on his way back to Central Asia at a site close to the present day town of Mansehra in North-West Pakistan.
