The Wedding of Leopold I of Belgium and Louise of Orléans (French: Le Mariage de Léopold Ier, roi de Belges, et de Louise d'Orléans) is an 1837 history painting by the French artist Joseph-Désiré Court. It depicts the wedding between Leopold I of Belgium and Louise of Orléans that took place at the Château de Compiègne on 9 August 1832. Leopold, the first King of Belgium with strong connections to the British Royal Family, made a dynastic match with Louise who was the eldest daughter of the French monarch Louis Philippe I. France had provided military support to Belgium against the Netherlands during recent fighting in the wake of the Belgian Revolution.
The painting was commissioned by Louis Philippe I to commemorate the event. Today the work hangs at the Château de Compiègne. A version also exists in the collection of the Musée de l'Histoire de France at the Palace of Versailles.
