Prince Guillaume, Hereditary Grand Duke of Luxembourg (given names: Guillaume Jean Joseph Marie; born 11 November 1981), has been heir apparent to the crown of Luxembourg since his father's accession in 2000.

Prince Guillaume was born in 11 November 1981 at the Grand Duchess Charlotte Maternity Hospital in Luxembourg City and is the eldest child of Grand Duke Henri of Luxembourg and his wife, Cuban-born Grand Duchess Maria Teresa. He was named after his father's youngest brother Prince Guillaume of Luxembourg. Guillaume has four younger siblings: Prince Félix, Prince Louis, Princess Alexandra and Prince Sébastien.

Guillaume's education includes Lycée Robert-Schumann in Luxembourg; Collège Alpin International Beau Soleil and Institut Le Rosey boarding schools in Switzerland; and Royal Military Academy Sandhurst, Camberley, England. He began his higher education studies in the United Kingdom where he studied at University College, Durham and Brunel University, both in England. In 2006 he entered Institut Philanthropos in Fribourg, Switzerland, where he spent a year studying philosophy and anthropology. He later studied letters and political science at the Institut Albert-le-Grand in Angers, receiving his bachelor's degree with honors in 2009. His degree was issued by Université d'Angers, as a result of a partnership agreement between the two schools.
