The Coronation Chair, also known as St Edward's Chair or King Edward's Chair, is an ancient wooden chair on which British monarchs sit when they are invested with regalia and crowned at their coronations. It was commissioned in 1296 by King Edward I to contain the Stone of Scone, which he had captured from the Scots. The chair was named after Edward the Confessor and for centuries it was kept in his shrine at Westminster Abbey.

The coronation of the monarch of the United Kingdom is an initiation ceremony in which they are formally invested with regalia and crowned at Westminster Abbey. It corresponds to the coronations that formerly took place in other European monarchies, which have all abandoned coronations in favour of inauguration or enthronement ceremonies. A coronation is a symbolic formality and does not signify the official beginning of the monarch's reign; de jure and de facto their reign commences from the moment of the preceding monarch's death or abdication, maintaining legal continuity of the monarchy.
