Emile Barnes (18 February 1892 – 2 March 1970) was a New Orleans jazz clarinetist.
Barnes studied under Lorenzo Tio Jr., Alphonse Picou, George Baquet, and Louis Nelson Delisle (also known as "Big Eye" Louis Nelson).
Active professionally in New Orleans by 1908, he was long well regarded locally for his bluesy and distinctively individualistic style.
Barnes was featured on several Folkways Records New Orleans compilation albums during the 1950s, and again in the early 60s as a solo artist.
When British trumpeter Ken Colyer jumped ship and visited New Orleans in 1953, he recorded with a pick-up band including Barnes.
