The House of Laborde de Monpezat is a French family, known since the seventeenth century, associated with the Danish Royal Family by marriage. In 1967 Henri de Laborde de Monpezat wed Princess Margrethe of Denmark, heir presumptive of the ruling House of Glücksburg. In the event of ascension to the Danish throne of their son or male-line descendant, the main branch of the Danish Royal Family will belong patrilineally to the Laborde de Monpezat lineage. However, it is unclear which name the royal family will use in this event.
