Woluwe-Saint-Pierre (French, pronounced [wolywe sɛ̃ pjɛʁ] ) or Sint-Pieters-Woluwe (Dutch, pronounced [sɪnt ˈpitərs ˈʋoːlyu.ə] ) is one of the 19 municipalities of the Brussels-Capital Region, Belgium. Located in the eastern part of the region, it is bordered by Etterbeek, Auderghem and Woluwe-Saint-Lambert, as well as the Flemish municipalities of Kraainem and Tervuren. In common with all of Brussels' municipalities, it is legally bilingual (French–Dutch).
As of 1 January 2022, the municipality had a population of 42,216 inhabitants. The total area is 8.94 km (3.45 sq mi), which gives a population density of 4,722/km (12,230/sq mi). It is mostly a well-to-do residential area, which includes the wide, park-lined, Avenue de Tervueren/Tervurenlaan, and the numerous embassies located near the Square Maréchal Montgomery/Maarschalk Montgomeryplein. Of the three streams that once crossed the municipality, only the Woluwe, a tributary of the Senne, can still largely be seen today.
