Prince Lorenz of Belgium, Archduke of Austria-Este (born 16 December 1955) is a member of the Belgian royal family as the husband of Princess Astrid of Belgium. He is the head of the House of Austria-Este, a cadet branch of the House of Habsburg-Lorraine; he has held this position since 1996.

Prince Lorenz was born at Belvedere Clinic in Boulogne-Billancourt, Hauts-de-Seine, France as the second child and eldest son of Robert, Archduke of Austria-Este, and his wife, Archduchess Margaret (née Princess Margherita of Savoy-Aosta). He is the grandson of Charles I of Austria, the last Emperor of Austria.

He and his uncle, Carl Ludwig, complained about the constitutional provision that prohibited members of the former ruling dynasty from running in the Austrian presidential elections, and the terms under which their family was banished from the country. Their subsequent appeal to the European Commission for Human Rights was ruled inadmissible by the court.^[1] Further, in June 2011, the Habsburg Law was repealed by the Austrian Parliament.

On 22 September 1984, at Church of Our Blessed Lady of the Sablon in Brussels, Prince Lorenz married Princess Astrid of Belgium, the only daughter of the then-Prince and Princess of Liège, later King Albert II and Queen Paola. The couple has five children:^[2][3][4]
