Jeffery Oliver Miller (born February 9, 1996) is an American trombonist, vocalist, composer, arranger and bandleader primarily known for his work in jazz and pop music.

He is the great-great grandnephew of Papa John Joseph, a New Orleans bass player who worked with Buddy Bolden (and notably passed away during an especially raucous performance of "When the Saints Go Marching In" with the Preservation Hall Jazz Band).

Although initially drawn to the drumset, Miller began to study the trombone around age ten or eleven, inspired by his middle school band director Keith Hart.

[12][13] He recorded on Jon Batiste's studio album Hollywood Africans as well as contributed trombone solos to John Legend's Grammy-nominated A Legendary Christmas (featuring Esperanza Spalding).

[1][3][5] In May 2020, he released his album Songs About Women, on which he both sang and played trombone alongside saxophonist Chris Bittner, pianist Sean Mason, drummer Brian Richburg Jr., and bassist Philip Norris.
