Leuven or Louvain is the capital and largest city of the province of Flemish Brabant in the Flemish Region of Belgium. It is located about 25 kilometres east of Brussels. The municipality itself comprises the sub-municipalities of Heverlee, Kessel-Lo, Leuven proper, Wilsele, Wijgmaal and part of Haasrode and Korbeek-Lo. It is the eighth largest city in Belgium, with more than 100,244 inhabitants.

The Kingdom of Belgium is divided into three regions. Two of these regions, Flanders and Wallonia, are each subdivided into five provinces. The third region, Brussels, does not belong to any province and nor is it subdivided into provinces. Instead, it has amalgamated both regional and provincial functions into a single "Capital Region" administration.
