The Trinity Altarpiece, also known as the Trinity Altar Panels, is a set of four paintings in oil on wood thought to have been commissioned for the Trinity College Kirk in Edinburgh, Scotland, in the late fifteenth century.
The four panels depict the following subjects:
- The Holy Trinity.
- A praying cleric, thought to be the contemporary Provost of Trinity College Kirk, Edward Bonkil, accompanied by two angels playing an organ.
- King James III of Scotland at prayer attended by Saint Andrew and a boy who may be the future King James IV. The royal arms of Scotland hang from a wall.
- Queen Margaret of Scotland at prayer attended by Saint Michael. Her royal arms decorate her lectern.
