Lester Raymond "Les" Brown (March 14, 1912 – January 4, 2001) was an American jazz musician who led the big band Les Brown and His Band of Renown for nearly seven decades from 1938 to 2000.

He enrolled in the Conway Military Band School (later part of Ithaca College) in 1926, studying with famous bandleader Patrick Conway for three years before receiving a music scholarship to the New York Military Academy, where he graduated in 1932. Brown attended college at Duke University from 1932–1936. There he led the group Les Brown and His Blue Devils, who performed regularly on Duke's campus and up and down the east coast.

Brown took the band on an extensive summer tour in 1936. At the end of the tour, while some of the band members returned to Duke to continue their education, others stayed on with Brown and continued to tour, becoming in 1938 the Band of Renown which recorded for Decca. He had planned to take a permanent job with Larry Clinton when the season ended, but club management wouldn't let him quit. At about that same time he switched labels to Bluebird, and an RCA Victor exec took interest in him, convincing him to organize a better band and getting him a booking in the Green Room of New York's Edison Hotel.
Starting with only twelve pieces, the orchestra quickly grew in both quantity and quality. Its greatest failing, however, was a lack of intimacy with its audience. Even the arrival of Doris Day in the summer of 1940 didn't make the band seem any warmer.
Doris had been working for Bob Crosby's group but had decided to quit after, reports say, a member of the band had made strong passes at her and frightened her. She fit right in with Brown's group, who were probably as respectable as swing musicians could be! Doris stayed for only a year, retiring, temporarily, to marry Jimmy Dorsey musician Al Jordan.

The band had nine other number-one hit songs, including "I've Got My Love to Keep Me Warm". In 1952-53, Brown was the orchestra leader on Day's radio program, The Doris Day Show, on CBS.
Les Brown and the Band of Renown performed with Bob Hope on radio, stage and television for almost fifty years. They did 18 USO Tours for American troops around the world, and entertained over three million people. Before the Super Bowls were televised, the Bob Hope Christmas Specials were the highest-rated programs in television history. Tony Bennett was "discovered" by Bob Hope and did his first public performance with Brown and the Band.
The first film that Brown and the band appeared in was Seven Days' Leave (1942) starring Victor Mature and Lucille Ball. Rock-A-Billy Baby, a low-budget 1957 film, was the Band of Renown's second, and in 1963 they appeared in the Jerry Lewis' comedy The Nutty Professor playing their theme song "Leapfrog".
Brown and the Band were also the house band for The Steve Allen Show (1959–1961) and the Dean Martin Show (1965–1972). Brown and the band performed with virtually every major performer of their time, including Frank Sinatra, Ella Fitzgerald and Nat King Cole.

Brown was inducted into the North Carolina Music Hall of Fame in 2010.
