Earl Kenneth Hines, universally known as Earl "Fatha" Hines (December 28, 1903 – April 22, 1983), was an American jazz pianist and bandleader. He was one of the most influential figures in the development of jazz piano and, according to one major source, is "one of a small number of pianists whose playing shaped the history of jazz".

Trumpeter Dizzy Gillespie, a member of the Earl Hines big-band along with Charlie Parker, wrote, "The piano is the basis of modern harmony. This little guy came out of Chicago, Earl Hines. He changed the style of the piano. You can find the roots of Bud Powell, Herbie Hancock, all the guys who came after that. If it hadn't been for Earl Hines blazing the path for the next generation to come, it's no telling where or how they would be playing now. There were individual variations but the style of ... the modern piano came from Earl Hines."
