Louis Jordan (July 8, 1908 – February 4, 1975) was a pioneering American jazz, blues and rhythm & blues musician, songwriter and bandleader who enjoyed his greatest popularity from the late 1930s to the early 1950s. Known as "The King of the Jukebox", Jordan was highly popular with both black and white audiences in the later years of the swing era. In 2004, Rolling Stone Magazine ranked him #59 on their list of the 100 Greatest Artists of All Time.

Louis Jordan was one of the most successful African-American musicians of the 20th century, ranking fifth in the list of the all-time most successful black recording artists according to Billboard magazine's chart methodology. Though comprehensive sales figures are not available, he scored at least four million-selling hits during his career. Jordan regularly topped the R&B "race" charts, and was one of the first black recording artists to achieve a significant "crossover" in popularity into the mainstream (predominantly white) American audience, scoring simultaneous Top Ten hits on the white pop charts on several occasions. After Duke Ellington and Count Basie, Louis Jordan was probably the most popular and successful black bandleader of his day. But in contrast to almost all of his colleagues of all races, he was a major personality in his own right, an all-round entertainer of enormous and diverse accomplishments.

Jordan was a talented singer with great comedic flair, and he fronted his own band for more than twenty years. He duetted with some of the biggest solo singing stars of his day, including Bing Crosby, Ella Fitzgerald and Louis Armstrong. Jordan was also an actor and a major black film personality -- he appeared in dozens of "soundies" (promotional film clips), made numerous cameos in mainstream features and short films, and starred in two musical feature films made especially for him. He was an instrumentalist who specialized in the alto saxophone but played all forms of the instrument, as well as piano and clarinet. A productive songwriter, many of the songs he wrote or co-wrote became influential classics of 20th-century popular music.
