Dharma Ratna Tuladhar, popularly known as Dharma Ratna Yami (Nepali: धर्मरत्न यमी) was a Nepalese government deputy minister, activist and Newa language writer[1] While serving eighteen years jail term, he changed his surname from Tuladhar to Yami (meaning an inhabitant of Kathmandu in Nepal Bhasa) and identified himself as Newa.

In Tibet, he came in contact with Mahapandit Rahul Sankrityayan; and under his influence and inspiration, he studied books on various subjects and began writing himself.

In 1948, he became a founder member of the Nepal Democratic Congress Party which was for overthrowing the Rana regime by any means, including armed uprising.

According to Koirala, Yami was inducted into the cabinet at the insistence of King Tribhuvan because of his experience in Tibet and social work, and that somebody from the Buddhist community of the Kathmandu Valley should be included in it.

His radical social and political views have led his contemporaries like missionary Father Marshall D. Moran, SJ to describe him as the most informative and interesting person in Kathmandu.

Yami was a prolific and multilingual writer and has published 21 books including novels, epics and an anthology of poems in Nepal Bhasa, Nepali, English and Hindi.
