List of knights grand cross of the Royal Guelphic Order

Below is an incomplete list of knights grand cross of the Royal Guelphic Order from the creation of the order in 1815 until 1837. A Hanoverian order, appointments have not been conferred by the British monarch (in their role as King of Hanover) since the death of King William IV in 1837, when the personal union of the United Kingdom and Hanover ended. After 1837 the order continued to be conferred by the Kingdom of Hanover, until the Kingdom was dissolved by Prussia in 1866. After this it became an order of the Royal House of Hanover.
