Henri (Luxembourgish: Henri Albert Gabriel Félix Marie Guillaume) is the current Grand Duke of Luxembourg, reigning since 7 October 2000. He is the eldest son of Grand Duke Jean and Princess Joséphine-Charlotte of Belgium, and a first cousin of Philippe, the king of the Belgians.
As the head of a constitutional monarchy, Grand Duke Henri's duties are primarily representative. However, he retains the constitutional power to appoint the prime minister and government, to dissolve the Chamber of Deputies, to promulgate laws and to accredit ambassadors.
Grand Duke Henri is commander-in-chief of the Luxembourg Army, in which he holds the rank of general.
