William Benton Overstreet (April 3, 1888 – June 23, 1935) was an American songwriter, bandleader and pianist in the early twentieth century. He was born in Atchison, Kansas. He directed McCabe's Georgia Troubadours in 1910, and by the mid-1910s was working in Kansas City, Missouri, directing the Lyric Theatre Orchestra. A prominent bandleader of the period, he also ran a group backing the "Rag Shouters" with singer Estelle Morris in Chicago. By that time, he was using the word "jass" to describe his music. He worked at the Grand Theatre in Chicago between 1916 and 1922, and then worked in Harlem and in touring shows in the 1920s.
