Najm ad-Din Kubra (Persian: نجم‌الدین کبری) was a 13th-century Khwarezmian Sufi from Khwarezm and the founder of the Kubrawiya, influential in the Ilkhanate and Timurid dynasty.

His method, exemplary of a "golden age" of Sufi metaphysics, was related to the Illuminationism of Shahab al-Din Yahya ibn Habash Suhrawardi as well as to Rumi's Shams Tabrizi.

[4] Because his followers were predominantly Sufi writers and gnostics, Kubra was given the title "manufacturer of saints" (in Persian: vali tarash) and his order was named the Kubrawiya.

He wrote numerous important works discussing the visionary experience, including a Sufi commentary on the Quran that he was unable to complete due to his death in 618/1221.

Kubra's work spread throughout the Middle East and Central Asia where it flourished for many years, until it gradually was taken over by other similar more popular ideologies and Sufi leaders.

The Kubrawiya found great development outside of Central Asia, but its influence and presence only lasted till the 15th/16th century, when it was overshadowed by the Naqshbandiya (another, more attractive Sufi group) during the Ottoman Empire, though a nominal following continued on.

[8] The Firdausi Kubrawi order was popularized in Bihar and Bengal region of India by Makhdoom Sharfuddin Ahmed Yahya Maneri Hashmi who is buried in Biharsharif.

Among his twelve students one can mention Najmeddin Razi, Sayfeddin Bakhezri, Majd al-Dīn Baghdādī, Ali ibn lala ghznavi[9] and Baha'uddin Walad, father of Jalaluddin Rumi.
