James Sylvester Scott was an American ragtime composer and pianist. He is regarded as one of the "Big Three" composers of classical ragtime along with Scott Joplin and Joseph Lamb.

Ragtime, also spelled rag-time or rag time, is a musical style that had its peak from the 1890s to 1910s. Its cardinal trait is its syncopated or "ragged" rhythm. Ragtime was popularized during the early 20th century by composers such as Scott Joplin, James Scott and Joseph Lamb. Ragtime pieces are typically composed for and performed on piano, though the genre has been adapted for a variety of instruments and styles.
