Shukra Raj Shastri (Devanagari: शुक्रराज शास्त्री) (born Shukra Raj Joshi) (1894-24 January 1941) was a Nepalese intellectual and fighter for democracy who became a martyr. He was one of the four martyrs of the revolution that brought down the Rana dynasty in Nepal. The other three were Dashrath Chand, Dharma Bhakta Mathema and Ganga Lal Shrestha.
Shastri was also a social reformer and author who wrote a number of books in Nepali and Nepal Bhasa.
Shastri was born in Varanasi, India. His father Madhav Raj Joshi and mother Ratna Maya Joshi were originally from Lalitpur. Madhav Raj was a leader of the Arya Samaj in Nepal, and was forced to live in exile in India for political reasons.
Shukra Raj was schooled in India, and he acquired the title Shastri after earning a Shastri degree from Dehradun. He became better known by this name than his actual surname Joshi.
Returning to Nepal, Shastri joined the democracy struggle. During a demonstration organized at Indra Chowk, Kathmandu by the Citizens' Rights Committee, he spoke out strongly against the Rana regime and demanded the people's rights. For this act, he was arrested and sentenced to six years' imprisonment.
