Patnam Subramania Iyer (1845 – July 31, 1902) was a composer and singer of Carnatic music. Subramaniya Iyer followed the traditions of the great composer Tyagaraja. He has left behind almost one hundred compositions. Subramaniya Iyer spent a long time in Chennapatnam (Chennai). This gave Subramaniya Iyer the prefix to his name. Many of his students such as Mysore Vasudevachar, Poochi Srinivasa Iyengar, Bhairavi Kempegowda and Tiger Varadachariar became famous composers and vocalists. His neighbour Maha Vaidyanatha Iyer was also a noted musician.
