The Flemish Region, usually simply referred to as Flanders, is one of the three regions of Belgium—alongside the Walloon Region and the Brussels-Capital Region. Covering the northern portion of the country, the Flemish Region is primarily Dutch-speaking. With an area of 13,522 km2 (5,221 sq mi), it accounts for only 45% of Belgium's territory, but 57% of its population. It is one of the most densely populated regions of Europe with around 490/km2 (1,300/sq mi).

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.
