Gopal Baba Walangkar, also known as Gopal Krishna Walangkar (1840–1904) is an early example of an activist working to release the untouchable people of India from their historic socio-economic oppression and is generally considered to be the pioneer of that movement. He developed a racial theory to explain the oppression and also published the monthly journal Vital-Vidhvansak, targeted at the Brahmanical Orthodoxy.
