Field-Marshal Shree Shree Shree Maharaja Sir Mohan Shumsher Jung Bahadur Rana (), GCB, GCIE, GBE (23 December 1885 – 6 January 1967) was the Shree Tin Maharajah and foreign minister of Nepal from 30 April 1948 until 12 November 1951.

He was the last prime minister from the Rana family, which had controlled Nepal for more than a century and reduced the monarchy to a figurehead. He was the son of the 5th Rana Maharaja of Nepal Chandra Shumsher and Bada Maharani Chandra Loka Bhakta Lakshmi Devi. He became prime minister at a time when the king, Tribhuvan  was attempting to assert himself. Tribhuvan wanted to establish a stronger monarchy and some democracy, which Mohan Shumsher opposed.

In 1950, Mohan Shumsher's policies against the monarchy forced Tribhuvan and his son Mahendra to flee to India with the help of the Indian Residency and the Indian government, which led Mohan Shumsher to proclaim Mahendra's three-year-old son Gyanendra  the king of Nepal.

Later in the revolution of 1951, Tribhuvan returned to Nepal after signing The Delhi Treaty between Mohan Shumsher, Tribhuvan and Nepali Congress thus restoring his throne and bringing the stately power back to the monarch. By the end of 1951, the king and his allies, the Nepali Congress had triumphed, and Mohan Shumsher and the rest of the Rana family lost power. The Ranas were deprived of all the hereditary offices and privileges conferred by king Surendra Bikram Shah on Jung Bahadur even though Mohan Shumsher still held the office of the prime minister for until several demonstrations by Ranas in an attempt to reestablish their rule and the opposition of the monarchy and Nepali Congress forced him to resign from his position.

On 14 December 1951, Mohan Shumsher went into self-imposed exile in India, and died in Bangalore in 1967, aged 81.
