John Knowles Paine (January 9, 1839 – April 25, 1906) was the first American-born composer to achieve fame for large-scale orchestral music. The senior member of a group of composers collectively known as the Boston Six, Paine was one of those responsible for the first significant body of concert music by composers from the United States. The Boston Six's other five members were Amy Beach, Arthur Foote, Edward MacDowell, George Chadwick, and Horatio Parker.
