Béla Anton Leoš Fleck (born July 10, 1958) is an American banjo player. An acclaimed virtuoso, he is an innovative and technically proficient pioneer and ambassador of the banjo, bringing the instrument from its bluegrass roots to jazz, classical, rock and various world music genres. He is best known for his work with the bands New Grass Revival and Béla Fleck and the Flecktones. Fleck has won 14 Grammy Awards and been nominated 33 times.

In 2020, he was inducted into the International Bluegrass Music Hall of Fame as a member of New Grass Revival.

A native of New York City, Fleck was named after Hungarian composer Béla Bartók, Austrian composer Anton Webern, and Czech composer Leoš Janáček. He was drawn to the banjo at a young age when he heard Earl Scruggs play the theme song for the television show Beverly Hillbillies and when he heard “Dueling Banjos” by Eric Weissberg and Steve Mandell on the radio. At the age of 15, he received his first banjo from his grandfather.
