There are two awards that each go by the name "Ramanujan Prize": the SASTRA Ramanujan Prize and the ICTP Ramanujan Prize for Young Mathematicians from Developing Countries.

The Shanmugha Arts, Science, Technology, Research Academy (SASTRA) Ramanujan prize is sponsored by the SASTRA academy based in South India, and is given annually to a mathematician not exceeding the age of 32 (the age at which Ramanujan died) for outstanding contributions to an area of mathematics influenced by S. Ramanujan. Awards carry a cash prize of $10,000. The following table summarizes awards to date.
