The Queen Mary Harp (Scottish Gaelic: Clàrsach na Banrìgh Màiri) 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, in South West Scotland. It is one of the three oldest surviving Gaelic harps, the others being the Lamont Harp and the Trinity College Harp.
