  Joseph de Riquet de Caraman, 17th Prince de Chimay (20 August 1808, Paris – 12 March 1886, London) was a Belgian diplomat and industrialist.
  
  ## Early life
  
  Joseph was the eldest son of François Joseph de Riquet de Caraman, prince de Chimay and his wife Thérésa Cabarrus (Madame Tallien), one of the leaders of Parisian social life during the Directory.
  
  ## Career
  
  He led the negotiations which led to a treaty of friendship between the Netherlands and Belgium following William I of the Netherlands' abjuration, which guaranteed Belgian independence. He also contributed to establishing Belgium's diplomatic relations with the Grand Duchy of Tuscany, the Kingdom of Naples, the Papal States and the German Confederation.
  
  In 1852 he acquired the Hôtel de la Pagerie at 17 quai Malaquais, in the 6th arrondissement of Paris, renaming it Hôtel de Chimay. It was sold in 1883 to the École des beaux-arts. In 1863 he built a theatre in his château de Chimay in Belgium, designed by Hector-Martin Lefuel and Cambon and inspired by Louis XV's theatre at the Palace of Fontainebleau.
  
  He financed the foundation of Scourmont Abbey on Chimay lands and in 1858 headed the consortium which founded the Compagnie de Chimay, one of the first Belgian railway companies, which built a line linking Chimay to Anor in France and Mariembourg.
