Henri (Luxembourgish: Henri Albert Gabriel Félix Marie Guillaume; born 16 April 1955) 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 the current King of the Belgians, Philippe.

Henri was born at Betzdorf Castle in eastern Luxembourg on 16 April 1955, the second child and first son of Jean, Hereditary Grand Duke of Luxembourg, and Princess Joséphine Charlotte of Belgium, and grandchild of Grand Duchess Charlotte and Prince Felix of Bourbon-Parma. The Prince's godparents were the Prince of Liège (his maternal uncle) and Princess Marie Gabriele, Countess of Holstein-Ledreborg (his paternal aunt).

Henri has four siblings: Archduchess Marie Astrid of Austria (born 1954), Prince Jean of Luxembourg (born 1957), Princess Margaretha of Liechtenstein (born 1957) and Prince Guillaume of Luxembourg (born 1963).

On 12 November 1964, when Henri was nine, his grandmother's abdication and his father's subsequent accession as Grand Duke made him heir apparent. As the Grand Duke's eldest son, he automatically took the title of Hereditary Grand Duke.
