The Boulevard Anspach (French) or Anspachlaan (Dutch) is a central boulevard in Brussels, Belgium, connecting the Place de Brouckère/De Brouckèreplein to the Place Fontainas/Fontainasplein. It was created following the covering of the river Senne (1867–1871), and bears the name of Jules Anspach, a former mayor of the City of Brussels.
The Boulevard Anspach is continued to the north by both the Boulevard Émile Jacqmain/Émile Jacqmainlaan and the Boulevard Adolphe Max/Adolphe Maxlaan, forming a "Y" crossroad at the Place de Brouckère. To the south, it crosses the Place de la Bourse/Beursplein about halfway through, and continues towards the Place Fontainas where it becomes the Boulevard Maurice Lemonnier/Maurice Lemonnierlaan.
