Nachimuthu Mahalingam (April 9, 1923 – October 2, 2014) was an Indian educationist, industrialist, philanthropist and prominent person in Tamil Nadu.
Mahalingam was born in Somanthurai Chittoor, Pollachi, in the family of Nachimuthu Palani Gounder and Rukmani.
Since his father Thiru P. Nachimuthu was a municipal chairman, Mahalingam showed interest into politics at very early in life.
He was elected as the member of the Tamil Nadu Legislative Assembly in 1952 as an Indian National Congress candidate for the first time at the age of 29.
Mahalingam had an important association with Sri Swami Satchidananda, the Indian swamiji who emigrated to the United States of America and founded the Integral Yoga Institutes.
