Dr. Kadri Gopalnath (11 December 1949 – 11 October 2019) was an Indian saxophonist and one of the pioneers of Carnatic music on the saxophone.

As a child, Gopalnath once saw the saxophone being played in the Mysore Palace band set. Upon hearing the vibrant tone of the saxophone, Gopalnath decided to master it. It took him nearly 20 years to conquer the complex western wind instrument, and he was eventually crowned as the "Saxophone Chakravarthy.

Many titles and honours had come his way, the most cherished being the Asthana Vidwan of Sri Kanchi Kamakoti Peetam, Sri Sringeri Sharadha Peetam, Sri Ahobila Mutt and Sri Pillayarpatti Temple. He was awarded the Padma Shri in 2004.

Gopalnath had the distinction of being the first Carnatic musician to be invited in the BBC Promenade concert in 1994, in the Royal Albert Hall at London. The Asian Music Circuit, U.K, sponsored his recital.
