T. Subrahmanian Thirumump (also spelled as Thirumunp) (12 June 1906 – 29 November 1984) was a poet, freedom fighter and one of the earliest communist leaders from Kerala, India.

He wrote many patriotic songs during the Indian independence movement, and later in his life he translated many famous Sanskrit works into Malayalam.

After completing his education at Payyanur High School, he wanted to go to Mangalore or Kozhikode for higher studies but his family denied it.

The incident in which Lala Lajpat Rai was harassed and the Congress meeting held in Payyanur lit up his patriotism.

Namboodiripad had called him padunna padaval (literally meaning singing sword) for inspiring the masses with his progressive ideals.

[4] When CPI approved the BT Ranadive Thesis that says armed revolution is the way of Liberation in India, he left communism and active politics, saying, "British imperial hegemony is over here, Is it not enough to win the rights of the peasants and workers through democratic means?

[7] Other literary works include Vandematharam, Vikasam, Navothanam (poetry collection), and translations of some selected poems from Vivekananda sahithya sarvaswam.

[8] His house named Ravipuram residence, acquired by the Kerala Agricultural University in 1980 was renovated in 2014, to be used as the Centre for Studies on Farming Culture.

[6] In 2020, in his memory, the Government of Kerala started the construction of the TS Thirumump Cultural Complex at Kasargod Madikai.
