George McClennon (died 1937, Chicago, Illinois, United States) was an American jazz clarinetist, singer, and dancer.
McClennon was the adoptive son of Bert Williams and worked in theater revues and in vaudeville in the 1910s. As a clarinetist, he specialized in the style known as gas pipe clarinet, using the instrument to make noises that sounded like animals or sound effects. He was able to dance wildly as he played for comic effect and often performed in blackface. He played with Eddie Heywood and Willie "The Lion" Smith, and recorded with a group called the Harlem Trio and under his own name for Okeh Records in 1924-1926. Sidemen on these recordings included Heywood, Buddy Christian, Bob Fuller, Charlie Irvis, John Lindsay, Tom Morris, and Clarence Williams. He died of tuberculosis in 1937.[1]
