Mangu Ram (14 January 1886 – 22 April 1980), known popularly as Babu Mangu Ram Chaudhry, was an Indian freedom fighter, a politician from Punjab and one of the founder members of the Ghadar Party.
In 1909, he immigrated to the United States and there became associated with the Ghadar Party. Upon his return to India in 1925, he became a leader of the low-caste people, organising them in opposition to the system of untouchability that oppressed them. He was instrumental in the foundation of the Ad-Dharmi Movement, an organisation dedicated to attaining equality for Untouchables. He was elected to the Punjab Legislative Assembly in 1946 and in 1972 received recognition in the form of a pension and an award from Indira Gandhi for his work towards Indian independence.
