Clark Virgil Terry Jr. (December 14, 1920 – February 21, 2015) was an American swing and bebop trumpeter, a pioneer of the flugelhorn in jazz, and a composer and educator.

He played with Charlie Barnet (1947), Count Basie (1948–51), Duke Ellington (1951–59), Quincy Jones (1960), and Oscar Peterson (1964-96). He was with The Tonight Show Band from 1962 to 1972. His career in jazz spanned more than 70 years, during which he became one of the most recorded jazz musicians, appearing on over 900 recordings. Terry also mentored Quincy Jones, Miles Davis, Herbie Hancock, Wynton Marsalis, Pat Metheny, Dianne Reeves, and Terri Lyne Carrington.

Terry was born to Clark Virgil Terry Sr. and Mary Terry in St. Louis, Missouri, on December 14, 1920. He attended Vashon High School and began his professional career in the early 1940s, playing in local clubs. He served as a bandsman in the United States Navy during World War II. His first instrument was valve trombone.

Blending the St. Louis tone with contemporary styles, Terry’s years with Basie and Ellington (who secretly recruited Terry away from Basie) in the late 1940s and 1950s established his prominence. During his period with Ellington, he took part in many of the composer’s suites and acquired a reputation for his wide range of styles (from swing to hard bop), technical proficiency, and good humor. Terry influenced musicians including Miles Davis and Quincy Jones, both of whom acknowledged Terry’s influence during the early stages of their careers. Terry had informally taught Davis while they were still in St Louis, and Jones during Terry’s frequent visits to Seattle with the Count Basie Sextet.
