The Fortress of Luxembourg refers to the former fortifications of Luxembourg City, the capital of the Grand Duchy of Luxembourg, which were mostly dismantled in 1867. The fortress was of great strategic importance for the control of the Left Bank of the Rhine, the Low Countries, and the border area between France and Germany.

The fortifications were built gradually over nine centuries, from soon after the city's foundation in the tenth century until 1867. By the end of the Renaissance, Luxembourg was already one of Europe's strongest fortresses, but it was the period of great construction in the 17th and 18th centuries that gave it its fearsome reputation. Due to its strategic location, it became caught up in Europe-wide conflicts between the major powers such as the Habsburg–Valois Wars, the War of the Reunions or the French Revolutionary Wars, and underwent changes in ownership, sieges, and major alterations, as each new occupier—the Burgundians, French, Austrian and Spanish Hapsburgs, and Prussians—made their own improvements and additions.

Luxembourg took pride in the flattering historical epithet of the "Gibraltar of the North" as a result of its alleged impregnability. By 1443 it had only been taken by surprise by Phillip the Good. In 1795, the city, expecting imminent defeat and for fear of the following pillages and massacres, surrendered after a 7-month blockade and siege by the French, with most of its walls still unbreached. On this occasion, advocating to extend the revolutionary wars across the French borders, the French politician and engineer Lazare Carnot explained to the French House of Representatives, that in taking Luxembourg, France had deprived its enemies of "....the best fortress in Europe after Gibraltar, and the most dangerous for France", which had put any French movement across the border at a risk. Thus, the surrender of Luxembourg made it possible for France to take control of the southern parts of the Low Countries and to annex them to her territory.
