Lonnie Liston Smith Jr. (born December 28, 1940)  is an American jazz, soul, and funk musician who played with such jazz artists as Pharoah Sanders and Miles Davis before forming Lonnie Liston Smith and the Cosmic Echoes, recording a number of albums widely regarded as classics in the fusion, smooth jazz and acid jazz genres.

Smith was born and raised in Richmond, Virginia, United States to a musical family; his father was a member of Richmond Gospel music group The Harmonizing Four, and he remembered groups such as the Swan Silvertones and the Soul Stirrers (featuring a young Sam Cooke) as regular visitors to the house when he was a child. He studied piano, tuba and trumpet in high school and college before receiving a B.S. in music education from Morgan State University in Baltimore in 1961. Smith has cited Charlie Parker, John Coltrane and Miles Davis as major influences in his youth. While still a teenager, Smith became well known locally as a backing vocalist as well as pianist in the Baltimore metropolitan area. During this period, he regularly performed with a number of his contemporaries, including Gary Bartz (alto), Grachan Moncur (trombone), and Mickey Bass (bass). He also backed a number of jazz singers (including Ethel Ennis) while performing in the house band at Baltimore’s Royal Theater shortly after receiving his degree.
