Mathabar Singh Thapa(Nepali: माथवरसिंह थापा) was the Prime Minister and Commander in chief of the Nepalese Army from 1843 December 25 - 1845 May 17, until he was murdered by his nephew Jung Bahadur Rana. He was the nephew of Bhimsen Thapa, who was falsely sentenced for imprisonment for the death of King Rajendra's six months old son. Mathabar Singh Thapa fled to Shimla after the execution of Bhimsen Thapa, to avoid his own execution as he was Bhimsen’s nephew. Four years later, the second queen of Rajendra, Queen Rajya Lakshmi, called him back and installed him as the Prime Minister. Mathabar Singh, however, enraged the queen by refusing to make her son, Ranendra Bikram, the king. The queen, in turn, had him shot by his own nephew Janga Bahadur Rana.

Not much is known of Mathabar Singh Thapa's childhood. He was born in Borlang, Gorkha. He was the son of Kaji Nayan Singh Thapa who was killed in the war against the Kingdom of Kumaon. He was a nephew of Bhimsen Thapa and also the maternal uncle of Jang Bahadur Rana. Through his mother's side, he was the grandson of Kaji Ranajit Pande, who was the son of Kaji Tularam Pande. Kaji Tularam Pande was a cousin of Kaji Kalu Pande.

Mathabar Singh Thapa, who was exiled to India when Bhimsen Thapa was supposedly found to be guilty of murdering the King Rajendra's son who was 6 months old, was asked to return to Nepal by the queen. Mathabar Singh Thapa arrived in Kathmandu Valley in 1843 April 17 where a great welcome was organized for him. After consolidating his position, he successfully led to the murder of all his political adversaries Karbir Pandey, Kulraj Pandey, Ranadal Pandey, Indrabir Thapa, Radabam Thapa, Kanak Singh Mahat, Gurulal Adhikari and many others, in several pretexts. The second queen of Rajendra, Queen Rajya Laxmi declared him Minister and Commander-In-Chief of the Nepalese army in 1843 December 25 believing he would help to usurp the power from Rajendra, her own husband, and make her own son, Ranendra as the king of Nepal.
