Israr Ahmad (19 December 1940 – 2 April 2010) was an Indian theoretical nuclear physicist and professor at Aligarh Muslim University since 1961.

He was founding director of the Center for Promotion of Science at the Aligarh Muslim University from its inception in 1985 to 1991, and chairman of its Department of Physics from 1988 to 1991.

He was one of the strong supporters of the Aligarh Movement and revived the mission of Sir Syed to promote modern education, especially science, among oriental students and seminaries.

To achieve this, with the support of Dr. Abdus Salam, he established the Centre for Promotion of Science (CPS) at AMU Aligarh in 1985, and was appointed as founder director of the center.

In 1864 Sir Syed Ahmed Khan started the Urdu journal Tahzibul Akhlaq to spread awareness of contemporary socio-economic and educational developments in the Muslim community.

Tahzibul Akhlaq was discontinued in 1881, but 100 years later, his ardent supporter, the then vice-chancellor Syed Hamid, revived it in 1981.

Ahmad took an interest in the project and its promotion and was appointed its editor in June 1986, taking over this position from Prof. Noorul Hasan Naqvi.
