The Hôtel van Eetvelde is a historic town house in Brussels, Belgium. It was designed by Victor Horta for Edmond van Eetvelde, administrator of Congo Free State, and built between 1895 and 1898, in Art Nouveau style. It is located at 4, avenue Palmerston/Palmerstonlaan in the Squares Quarter. Two extensions, also designed by Horta, were added between 1898 and 1901.
Together with three other town houses 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 that Horta designed before 1900.
