Princess Louise d'Orléans (Louise Victoire Marie Amélie Sophie; 19 July 1869 – 4 February 1952) was a French princess of the House of Orléans and a member of the Royal Family of Bavaria. Throughout her life, Louise remained very close to her first cousin, Archduchess Marie Valerie of Austria.
In Paris on 4 May 1897, her mother, the famed duchesse d'Alençon, died in a fire at a charity bazaar (the Bazar de la Charité); she had refused rescue attempts, insisting that the girls working with her at the bazaar be saved first.
