Tiger Varadachariar (1876–1950) was a Carnatic music vocalist from the Indian state of Tamil Nadu. M. D. Ramanathan was his student. Masilamani and Pedda Singaracharyulu encouraged him in his musical pursuits, and he studied under Patnam Subramania Ayyar for three years from the age of fourteen. However, financial family constraints required the young Varadachariar to take a position with the Survey Department at Calicut. He continued to pursue his musical interests, however, and when living in Mysore, he attracted the attention of Krishnaraja Wodeyar, who honoured him with the title of 'Tiger' and presented him with a 'thoda'. Tiger Varadachari had lived for many years in Kaveripatnam then Salem District (now Krishnagiri). His humble home is still available as unaltered in Periyar St, Kaveripatnam. Many of Varadachariar's family members also pursued careers in music. His father Ramanujachariar was a musical discourser, his brother K.V. Srinivasa Ayyangar was a musicologist, and another brother K.V. Krishnamachariar was a veena player. Varadachariar also noted that he learned much from the singing of his sister.
