The Bellevue Avenue/Casino Historic District encompasses a one-block section of Bellevue Avenue in Newport, Rhode Island. Although Bellevue Avenue is best known for the large number of Gilded Age mansions which line it, especially further south, this block is a coherent collection of commercial buildings at the northern end of the mansion row. It is anchored around the Newport Casino, now the International Tennis Hall of Fame, and includes three other buildings on the east side of Bellevue Avenue between Memorial Boulevard and East Bowery Street.
