Ritabrata Munshi (born 14 September 1976 in Calcutta (Kolkata), West Bengal) is an Indian mathematician specialising in number theory.

In a series of papers published in 2015[2][3][4] he introduced a new approach, based on the circle method, and was able to establish sub-convex bounds for genuine degree three L-functions.

Munshi obtained PhD degree from Princeton University in 2006 under the guidance of Andrew John Wiles.

Munshi was awarded the Swarna-Jayanti fellowship by the Department of Science and Technology, Government of India in 2012.

For his outstanding contributions to analytic aspects of number theory, he was awarded the Infosys Prize 2017 in Mathematical Sciences.
