Keyon Karim Harrold (born November 18, 1980) is an American jazz trumpeter, vocalist, songwriter, and producer.

Keyon Harrold was born and raised in Ferguson, Missouri, United States, one of 16 children in a family of musicians. Harrold graduated from the School of Jazz at The New School. Harrold counts Miles Davis' second great quintet, Prince, Common, Dr. Dre and J Dilla as influences.

Harrold's first professional gig was as a trumpeter with Common, an audition he secured on the recommendation of New School classmate Robert Glasper. A mentee of trumpeter Charles Tolliver, Harrold performed as part of Charles Tolliver Big Band on the studio album With Love (2006) and concert release Emperor March: Live at the Blue Note (2009).

During this period, Harrold became a notable crossover performer, becoming a staple of New York jazz clubs as well as providing instrumentation for recordings by JAY-Z, Beyoncé, 50 Cent, Anthony Hamilton, Gregory Porter, Mac Miller, Mary J. Blige and Maxwell. Harrold has also toured with Cirque du Soleil's Michael Jackson: The Immortal World Tour, Rihanna, Eminem, Gregory Porter, D’Angelo, Maxwell and Mary J. Blige.

Harrold supplied all of the trumpet playing in Don Cheadle’s Miles Davis biopic Miles Ahead, playing to match Cheadle’s on-screen performance as well as the character of Junior, portrayed by LaKeith Stanfield. The soundtrack to the film won a Grammy Award for Best Compilation Soundtrack for Visual Media.

Harrold’s first solo album, Introducing Keyon Harrold, was released in 2009. AllMusic praised the album, saying "it bodes well for his bright future" as one of "the leading jazz trumpet players of a new generation." Harrold performed at The White House as part of Common's Tiny Desk Concert for NPR in 2016. A follow-up to his first album, The Mugician, was released on September 29, 2017 to positive reviews.

In August 2020, he contributed to the live streamed recording of the singer Bilal's EP VOYAGE-19, created remotely during the COVID-19 lockdowns. It was released the following month with proceeds from its sales going to participating musicians in financial hardship from the pandemic.
