Jai Narayan Vyas (18 February 1899 – 14 March 1963) was an Indian politician and the third chief minister of the State of Rajasthan.

He was born on 18 February 1899 in a Brahmin family[1] to Pandit Sewaramji Vyas and Shrimati Gopi Devi in Jodhpur.

Vyas and other Jodhpuri political activists formed the Marwar Hitkarni Sabha (Marwar Improvement Society) in the early 1920s in Jodhpur State, aimed at freeing the state from the rule of "aliens": a chief minister and other non-Jodhpuri officials both Indian and English.

Its motto was "Marwar [Jodhpur] for the Marwaris" and its design to protect local interests from the effects of administrative reform.63 The maharaja gave the Sabha his blessing, while Vyas saw his role in it as his first contribution to the freedom movement.

Later he formed the Jodhpur Praja Mandal (1934) with Bhanwarlal Sarraf, the Youth League, and the Marwar Lok Parishad (1938) with inspiration of Subhashchander Bose.
