Euday Louis Bowman (November 9, 1886 – May 26, 1949) was an American pianist and composer of ragtime and blues who represented the style of Texas Ragtime. He is chiefly remembered as the composer of the highly popular "Twelfth Street Rag", a ragtime composition from 1914 out of a series of rags that Bowman wrote during or after a period in which he worked as a pianist in bordellos of Kansas City. These pieces, including "Sixth Street Rag", "Tenth Street Rag", "Eleventh Street Rag" and "Twelfth Street Rag," were named after streets of Fort Worth's redlight district.
