Dharma Ratna Yami (Devanagari: ???? ???? ???) (born Dharma Ratna Tuladhar) (18 August 1915 – 10 September 1975) was a Nepalese social activist, author and government deputy minister known for his radical views on social mores.While serving eighteen years jail term, he changed his surname from Tuladhar to Yami (meaning an inhabitant of Kathmandu in Nepal Bhasa) in order to break the culture of silence by symbolizing that he had shed his caste and just identified himself as the common citizen of Kathmandu.
He realized the bad impact of the existing social practices of those times based on caste system.
This message helped other political prisoners in the jail to unite and organize oppressed communities against the Rana rulers.
