Luxembourg (Lëtzebuerg ; Luxembourg; Luxemburg), officially the Grand Duchy of Luxembourg, is a small landlocked country in Western Europe. It borders Belgium to the west and north, Germany to the east, and France to the south. Its capital and most populous city, Luxembourg, is one of the four institutional seats of the European Union (together with Brussels, Frankfurt, and Strasbourg) and the seat of several EU institutions, notably the Court of Justice of the European Union, the highest judicial authority. Luxembourg's culture, people, and languages are highly intertwined with its French and German neighbors; while Luxembourgish is legally the only national language of the Luxembourgish people, French and German are also used in administrative and judicial matters and all three are considered administrative languages of the country.

With an area of 2,586 km2, Luxembourg is one of the smallest countries in Europe, and the smallest not considered a microstate. In 2022, it had a population of 645,397, which makes it one of the least-populated countries in Europe, albeit with the highest population growth rate; foreigners account for nearly half the population. Luxembourg is a representative democracy headed by a constitutional monarch, Grand Duke Henri, making it the world's only remaining sovereign grand duchy.
