William Benton Overstreet (April 3, 1888 – June 23, 1935) was an influential American songwriter, bandleader, and pianist in the early twentieth century. Born in Atchison, Kansas, Overstreet directed McCabe's Georgia Troubadours in 1910 and later worked in Kansas City, Missouri, where he directed the Lyric Theatre Orchestra. He was a prominent bandleader, leading a group that backed the "Rag Shouters" with singer Estelle Morris in Chicago. Overstreet was one of the early adopters of the term "jass" to describe his music.

He worked at the Grand Theatre in Chicago from 1916 to 1922 and later in Harlem and on touring shows during the 1920s. As a songwriter, Overstreet was recognized by Langston Hughes as one of the "better poets of jazz." He wrote "The 'Jazz' Dance," published in 1917, which was recorded by W. C. Handy's Orchestra and marked the first known use of "jazz" in a song title. Overstreet collaborated with James "Slap Rag" White and Billy Higgins, with whom he composed the hit song "There'll Be Some Changes Made," published in 1921 and recorded by artists such as Ethel Waters, Fats Waller, and Billie Holiday.

By 1930, Overstreet was working as a music teacher in Milwaukee, Wisconsin, and continued to record as a piano accompanist into the early 1930s. He passed away on June 23, 1935, in New York.
