Ayatallah Aqa Syed Ahmed Rizvi, or simply Razavi (Urdu: آیت اللہ آقا سید احمد رضوی کشمیری; c. 1901 – c. 1965), was a Shiite Islamic jurist, religious reformer, and scholar who lived in Srinagar, Kashmir.

He was a descendant of Shi'ite eighth Imam Ali al-Rizha, the son of Imam Musa al-Kadhim, through one of the great saints and religious propagators Mir Aqa Syed Hussein Rizvi Qommi, who went to Kashmir from Qom, Iran in the year 821 A.H., during the reign of Sultan Sikander who appointed him as mentor of his son, Sultan Zain-ul-Abidin.

From Lucknow, he went for further studies to the city of Najaf in Iraq, which has been seen as a centre of Shiite Islamic seminaries and focus of spiritual subjects for almost fourteen hundred years.

Ayatollah Syed Ahmed Rizvi's spiritual education was provided by Ali Tabatabaei,[4] a significant figure of Shiite Gnosticism.

At another place, Ayatollah Syed Abdul Karim Kashmiri had mentioned him as a great man and a strong (spiritual personality), who remained confined to his room and had idealistic manners.

a person named Ghulam Hussein Makhmoor, who was a government official posted at Jammu almost 300 kilometers away from Srinagar City, had sent a letter to Ayatollah Aqa Syed Ahmed, seeking instructions from him in a complicated matter.

But he reportedly found Ayatollah Ahmed Kashmiri's reply to his letter at his bed, on the same evening, with no signs of any disturbance or unwanted entry present.
