Tiger Varadachariar (1876–1950) was a Carnatic music vocalist from what is now the Indian state of Tamil Nadu.
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'.
'Nidu Charanamule' (Simhendramadyamam) under the signature of Tyagaraja is actually a composition of the 'Three musketeers of Kaladipet', the Tiger Brothers.
