The royal mantle (Dutch: Koningsmantel) of the Netherlands is worn only by the Dutch monarch at their inauguration. As the Dutch monarch is never crowned but inaugurated, its more appropriate to speak of a royal mantle than a coronation mantle.

The royal mantle of Netherlands is a red velvet trimmed coat lined with white ermine and 83 Dutch lions embroidered with gold threads.

It was last worn at the inauguration of King Willem-Alexander.
