Ustad Vilayat Khan (28 August 1928 – 13 March 2004) was an Indian classical sitar player. Along with Imdad Khan, Enayat Khan, and Imrat Khan, he is credited with the creation and development of gayaki ang (an attempt to mimic vocal music) on the sitar. He recorded his first 78-RPM disc at the age of 8, and gave his last concert in 2004 at the age of 75.

Vilayat was born in Gouripur, Mymensingh in then East Bengal in British India and current Bangladesh. His father Enayat Khan was recognised as a leading sitar and surbahar (bass sitar) player of his time, as had been his grandfather, Imdad Khan, before him. He was taught in the family style, known as the Imdadkhani gharana or Etawah Gharana, after a small city close to Agra where Imdad Khan lived.
