Jai Bhim is a slogan and greeting used by followers of B. R. Ambedkar, an Indian politician, social reformer and first Law and Justice Minister of India. It refers to Ambedkar's given name Bhimrao. In 1935, Jai Bhim was conceived and developed by Babu L. N. Hardas (1904–1939), a staunch follower of Ambedkar, and the secretary of Samata Sainik Dal. However, its origin is obscure and may date as far back as 1818, well before Ambedkar's birth.

Bhimrao Ramji Ambedkar was an Indian jurist, economist, social reformer and political leader who headed the committee drafting the Constitution of India from the Constituent Assembly debates, served as Law and Justice minister in the first cabinet of Jawaharlal Nehru, and inspired the Dalit Buddhist movement after renouncing Hinduism.
