Maastricht (Dutch: [maːˈstrɪxt];Limburgish (incl. Maastrichtian): Mestreech [məˈstʀeˑx]; French: Maestricht (archaic); Spanish: Mastrique (archaic)) is a town and a municipality in the southeast of the Netherlands. It is the capital city of the province of Limburg.

Maastricht is located on both sides of the Meuse river (Dutch: Maas), at the point where the Jeker River (French: Geer) joins it.

In history Maastricht developed from a Belgic settlement, that in the Gallic Wars was conquered by the Romans and thus became a Roman settlement, to a religious centre, a garrison city and an early industrial city. Nowadays, it is known as an especially cultured city (including local folklore) and education. Maastricht's rich history shows from the fact that in this town no fewer than 1677 national heritage sites (Rijksmonumenten) are located, which is the second highest number in a Dutch town, after Amsterdam. Furthermore, it has become known, by way of the Maastricht Treaty, as the birthplace of the European Union, European citizenship, and the single European currency, the euro. The town is popular with tourists for shopping and recreation, and has a large growing international student population. Maastricht is a member of the Most Ancient European Towns Network and is part of the Meuse-Rhine Euroregion, which includes nearby cities Aachen, Eupen, Hasselt, Liège and Tongeren.
