The Hôtel van Eetvelde is a town house designed in 1895 by Victor Horta for Edmond van Eetvelde, administrator of Congo Free State. It is located at 4, avenue Palmerston/Palmerstonlaan in Brussels, Belgium.
Together with three other townhouses of Victor Horta, including Horta's own house and workshop, it was added to the UNESCO World Heritage list in 2000, as the core of epoch-making urban residences Victor Horta designed before 1900.
