Frederick Dewayne Hubbard (born April 7, 1938 in Indianapolis, Indiana) is an American jazz trumpeter.
In his youth, Hubbard associated with various musicians in Indianapolis, including Wes Montgomery and Montgomery's brothers. Chet Baker was an early influence, although Hubbard soon aligned himself with the approach of Clifford Brown (and his forebears: Fats Navarro and Dizzy Gillespie).
Hubbard's jazz career began in earnest after moving to New York City in 1958. While there, he worked with Sonny Rollins, Slide Hampton, J. J. Johnson, Philly Joe Jones, Oliver Nelson, and Quincy Jones, among others. He gained attention while playing with the seminal hard bop ensemble Art Blakey and the Jazz Messengers, appearing on such albums as Mosaic, Buhaina's Delight, and Free For All. He left the Messengers in 1964 to lead his own groups and since that time has maintained a high profile as a bandleader or featured as a special guest, but never merely a sideman.
Along with two other trumpeters also born in 1938, Lee Morgan (d. 1971) and Booker Little (d. 1961), Hubbard exerted a strong force on the direction of 1960s jazz. He recorded extensively for Blue Note Records: eight albums as a bandleader, and twenty-eight as a sideman.  Most of these recordings are regarded as classics. Hubbard appeared on a few early avant-garde landmarks (Ornette Coleman's Free Jazz, Eric Dolphy's Out to Lunch and John Coltrane's Ascension), but Hubbard never fully embraced free jazz, though it has influenced his playing.
