A royal mantle, or more simply a Mantle, is a garment normally worn by emperors, kings or queens as a symbol of authority. When worn at a coronation, such mantles may be referred to as coronation mantles. Many princes also wear such a mantle.

The Robe Royal (also known as the Pallium Regale, Imperial Mantle or Dalmatic Robe) is a robe worn by the British monarch when they are crowned at their coronation. It is donned just before the monarch is invested with the Orb, Ring and Sceptres. It is worn during the crowning and paying of homage.

A Coronation Mantle or pallium made of 'cloth of gold'; embroidered coloured floss silks with the national emblems of the United Kingdom including roses of England, thistles of Scotland, shamrocks of Ireland, crowns, eagles, olive branches and passionflowers. Lined in red silk satin.

In the medieval era, another type of cloak was common for finer purposes – The mantle. The distinction between the cloak and the mantle appears to be one of status. The cloaks were worn for protection, while the mantles seem to have been largely worn for display as a symbol of status for the upper-classes.
