Pearay Mohan Dattatreya (c. 1895 - 23 December 1936) was an Indian lawyer, senior assistant editor of The Tribune, and author of An Imaginary Rebellion and How It was Supressed (1920), published shortly after the release of the Indian Congress report on the Punjab disturbances of 1919, and in which included a foreword by Lala Lajpat Rai.

[1][2] In 1914 he co-authored with the journalist, Bishan Sahai Azad, a text in Urdu on the story of the war in Europe, titled Fasānah-i-Jung-i-Yurap.

[5][4] In it, he criticised the British Raj for fabricating enemies and situations for the purpose of expanding harsh laws such as the Rowlett Act.

[2][7] Mohan brought several cases to court, including some against the Railway for reserving special seats for Anglo-Indians on trains.
