Sundara Sastri Satyamurti (19 August 1887 – 28 March 1943) was an Indian independence activist and politician. Born in 1887 in Thirumayam in the princely state of Pudukkottai, Satyamurti studied at Maharajah's College, Madras Christian College, and the Madras Law College. After practicing as a lawyer for some time, Satyamurti entered politics at the suggestion of S. Srinivasa Iyengar, a leading lawyer, and politician, who later became his mentor. He was much-admired for his orotundity and was one of the leading politicians of the Indian National Congress from the Madras Presidency, alongside S. Srinivasa Iyengar, C. Rajagopalachari, and T. Prakasam. Satyamurti was regarded as the mentor of K. Kamaraj, who was the Chief Minister of Madras State from 1954 to 1962. Satyamurti participated in protests against the Partition of Bengal, Rowlatt Act, the Jallianwala Bagh massacre, and the Simon Commission. Satyamurti was the President of the provincial wing of the Swaraj Party from 1930 to 1934 and the Tamil Nadu Congress Committee from 1936 to 1939. He was a member of the Imperial Legislative Council from 1934 to 1940 and was the Mayor of Madras from 1939 to 1943. Satyamurti was jailed in 1942 for his active participation in the Quit India Movement. He was later released, but died on 28 March 1943, due to a heart attack.
