Navaratna Srinivasa Rajaram (22 September 1943 – 11 December 2019) was an Indian academic.He is notable for propounding the "Indigenous Aryans" hypothesis, asserting that the Vedic period was extremely advanced from a scientific view-point, and claiming of having deciphered the Indus script.

[9] He advocated the Indigenous Aryans hypothesis and rejected Indo-Aryan migration theory as a fabricated version of history devised for missionary and colonial interests, and later propounded by left-liberals and Marxists.

[16][13] Asko Parpola, professor of Indology at Helsinki University, commented:[5] It is sad that India's heritage should be exploited by some individuals – usually people with little or no academic credentials – who for political or personal motives are ready even to falsify evidence.

[17] Speaking from the chair of the President, on the occasion of the 2001 session of Indian History Congress, as to the recent advances in the deciphering of the Indus Script, Mahadevan noted:[4] .....He recognises that he has to demolish the current theories if the model of decipherment presented by him is to be accepted.

The method is so flexible and easy to follow that one can, without much effort, read into the Indus texts almost any mathematical formula...Thapar noted Rajaram's writings to resemble nineteenth century tracts that were evidently unfamiliar with tools of historiography but were sprinkled with programming references; so as to suggest scientific objectivity.

[19] Michael Witzel noted him to be an autochthonous writer, whose books were a mythological rewrite of history and were designed for the expatriate Indians of the 21st century, who sought a " largely imagined, glorious but lost distant past".
