The Ixelles Ponds (French: Étangs d'Ixelles) or Elsene Ponds (Dutch: Vijvers van Elsene) are two freshwater ponds in the Brussels municipality of Ixelles. The ponds we can see today are those spared by a 19th-century campaign of drying the wetlands of the Maalbeek valley between La Cambre Abbey and Eugène Flagey Square.
