Murugesu Sivasithamparam (20 July 1923 – 5 June 2002) was a leading Sri Lankan Tamil politician, Member of Parliament and Deputy Speaker.

A delimitation commission in the late 1950s created a new electoral district for Udupiddy from parts of Point Pedro.

[3][4] Sivasithamparam took part in the 1961 satyagraha organised by the Illankai Tamil Arasu Kachchi (Federal Party).

[citation needed] Sivasithamparam was delivering leaflets along with other leading Tamil politicians (A. Amirthalingam, V. N. Navaratnam, K. P. Ratnam and K. Thurairatnam) in 1976 when they were all arrested on government orders.

All the defendants were acquitted after a famous trial at bar case in which 72 Tamil lawyers including S. J. V. Chelvanayakam and G. G. Ponnambalam acted for the defence.

[citation needed] Sivasithamparam was the TULF's candidate for Nallur at the 1977 parliamentary election which he won with the largest majority in the country.

[citation needed] During the 1983 Black July riots, Sivasithamparam's home and cars in Norris Canal Road, Colombo were burnt.

[citation needed] Sivasithamparam and all other TULF MPs boycotted Parliament from the middle of 1983 for a number of reasons: they were under pressure from Sri Lankan Tamil militants not to stay in Parliament beyond their normal six-year term; the Sixth Amendment to the Constitution of Sri Lanka required them to swear an oath unconditionally renouncing support for a separate state; and the Black July riots in which up to 3,000 Tamils were murdered by Sinhalese mobs.

M. G. Ramachandran, the Chief Minister of Tamil Nadu, gave the family a flat to stay in.

Sivasithamparam survived an assassination attempt on 13 July 1989 but A. Amirthalingam and V. Yogeswaran, his fellow TULF leaders, were killed in the incident.
