Lester Rallingston "Shad" Collins (June 27, 1910 – June 6, 1978) was an esteemed American jazz trumpeter, composer, and arranger. Born in Elizabeth, New Jersey, he was the son of a clergyman and acquired the nickname "Shad" in his teens. By the late 1920s, Collins had joined Charlie Dixon's band and subsequently performed with pianist Eddie White. In 1931, he became a member of Chick Webb's band, marking the beginning of a prolific career in jazz.

Throughout the 1930s, Collins played with several prominent bands, including those led by Benny Carter, Don Redman, and Count Basie, with whom he performed at the notable From Spirituals to Swing concerts in New York City in 1938 and 1939. In 1941, he replaced Dizzy Gillespie in Cab Calloway's band, remaining until 1943 and returning from 1944 to 1946. Collins also collaborated with Oran "Hot Lips" Page in the 1940s.

In the 1950s, Collins played with Jimmy Rushing and Sam "The Man" Taylor, adapting his style to the rhythm and blues music that was gaining popularity. He continued to perform on a part-time basis during the 1960s. As a composer and arranger, Collins was known for the frequently recorded tune "Rock-a-Bye Basie."

Shad Collins passed away in New York City at the age of 67. His contributions to jazz, particularly through his work with leading bands of the era, have left a lasting legacy in the world of music.
