Nachimuthu Kamarasan (/kɑːmʌrɑːsʌn/ 29 November 1942 – 24 May 2017) was an Indian poet and lyricist who worked on Tamil-language films. Kamarasan was born in Meenakshipuram in Bodi at Theni district to Nachimuthu and Lakshmi Ammal. In 1964, when he was a student of Thiagarasar Arts College, Madurai, he participated in the anti-Hindi protest and was imprisoned. He has a Master's Degree and worked as a Tamil Lecturer at Uttampalayam Haji Karutha Rauthar College and as an Officer in the Department of Translation in the Tamil Nadu Government Secretariat. Though Kamarasan started writing poems in traditional verses with Surya Gandhi, he later switched to writing poems in formats like image poetry, free verse. Impressed by his poem compilation Karuppu Malargal, M. G. Ramachandran gave Kamarasan an opportunity to write lyrics for his film Needhikku Thalaivanangu and wrote his first film song "Kanavugale" and went on to write many songs for Ramachandran which he felt gave him the much needed freedom to write songs. Despite writing songs for films, he was not happy with the industry the way they treated him and other lyricists, for which he said "I used to make garlands and suddenly went to cut grass".
