The Lamont Harp, or Clàrsach Lumanach (also known as the Caledonian Harp or Lude Harp) is a Scottish Clarsach currently displayed in the National Museum of Scotland. It is believed to date back to the 15th century, and to have originated in Argyll. Along with the Queen Mary Harp and the Trinity College harp, it is one of the only three surviving medieval Gaelic harps.
