The Palais Vaissier (also called the Château Vassier or Palais du Congo), was a large Orientalist mansion in Tourcoing, Nord, (France), which served as the distinctive home of industrialist Victor Vaissier. It was designed by French architect Édouard Dupire-Rozan and built in 1891–92, but was demolished in 1929. Two of its outbuildings, the residences of its concierge and the gardener, have been preserved, however, and can be viewed today from the street.
