Kumar Gandharva or Shivaputra Siddharamayya Komkalimath (8 April 1924 - 12 January 1992) was a Hindustani classical singer, well known for his unique vocal style and his refusal to be bound by the tradition of any gharana.

The name Kumar Gandharva is a title given to him when he was a child prodigy; a Gandharva is a musical spirit in Hindu mythology.

Kumarji also experimented with other forms of singing such as Nirguni bhajans (Devotional songs), folk songs, and with both ragas and presentation, often going from fast to slow compositions in the same raga.

He is remembered for his great legacy of innovation, questioning tradition without rejecting it wholesale, resulting in music in touch with the roots of Indian culture, especially the folk music of Madhya Pradesh.

His innovative approach towards music led to the creation of new ragas from combinations of older ragas.

His singing in faster tempos, particularly his mastery over madhya-laya, was widely revered.

Pt. Kumar Gandharva was a musicologist as well.

Kumar Gandharva was awarded the Padma Bhushan in 1977 and India's second highest civilian honour the Padma Vibhushan in 1990.

'Hans Akela' is a 78 minutes documentary on Pandit Kumar Gandharva made by Films Division Govt. of India with interviews with various people - wife, friends, students.
