The Place Fontainas (French) or Fontainasplein (Dutch) is a square in central Brussels, Belgium. It was created following the covering of the river Senne (1867–1871). It is named in honour of André-Napoléon Fontainas, a former mayor of the City of Brussels.
The square lies at the conjunction of the Boulevard Anspach/Anspachlaan to the north with the Boulevard Maurice Lemonnier/Maurice Lemonnierlaan to the south, in the Midi–Lemonnier or Stalingrad Quarter (southern part of the City of Brussels). It is served by the premetro (underground tram) station Anneessens on lines 4 and 10.
