Liège (French: [ljɛʒ] ; Walloon: Lîdje [liːtʃ]; Dutch: Luik [lœyk] ; German: Lüttich [ˈlʏtɪç] ) is the easternmost province of the Wallonia region of Belgium.

Liège Province is the only Belgian province that has borders with three countries. It borders (clockwise from the north) the Dutch province of Limburg, the German states of North Rhine-Westphalia and Rhineland-Palatinate, the Luxembourgish canton of Clervaux, the Belgian Walloon (French-speaking) provinces of Luxembourg, Namur and Walloon Brabant and the Belgian Flemish (Dutch-speaking) provinces of Flemish Brabant and Limburg.

Part of the eastern-most area of the province, bordering Germany, is the German-speaking region of Eupen-Malmedy, which became part of Belgium in the aftermath of World War I.

The capital and the largest city of the province is the city of the same name, Liège. The province has an area of 3,857 km (1,489 sq mi), and a population of 1.12 million as of January 2024.

The modern borders of the province of Liège date from 1795, which saw the unification of the Principality of the Prince-Bishopric of Liège with the revolutionary French Department of the Ourthe (sometimes spelled Ourte). (Parts of the old Principality of Liège also went into new French départements Meuse-Inférieure, and Sambre-et-Meuse.)

The province of Ourthe, as it was known then, was under French control during the reign of Napoleon, who visited the city during one of his campaigns. Napoleon ordered the destruction of its vineyards in order to prevent the Liège wine industry from competing with those elsewhere in France.

Following Napoleon's fall from power in 1815, Liège became part of the Kingdom of the Netherlands, while eastern half of modern Verviers became part of the Kingdom of Prussia. Liège University scholars helped to write the new Dutch constitution after the Napoleonic Wars. Despite these contributions there was a widespread perception among the people of Liège that they were discriminated against by the Dutch government due to religious and language differences.

In September 1830, rumors spread of a revolt in Brussels to expel the Dutch. Liège intellectuals responded to these events by contacting Walloon scholars living in Paris to discuss Belgian independence. A militia was formed to press these demands led by Charlier "Wooden Leg" leading (eventually) to the formation of an independent Kingdom of Belgium.

In the 19th century, the province was an early center of the Industrial Revolution. Its rich coal deposits and steel factories helped Belgium to form the basis of the region's increasing economic power.

During the 20th century, due to Liège's borders with Germany, it saw fierce fighting in both World Wars. In World War I, Liège's strong line of reinforced concrete military forts temporarily halted the German advance through Belgium, giving time to construct trenches in Flanders which subsequently saw some of the worst fighting of that war. It also saw some of the war's worst civilian casualties as the Imperial German Army performed collective punishments against local villagers for acts of resistance. In 1925 the East Cantons and Neutral Moresnet, that had become part of Belgium as a result of the Treaty of Versailles, were absorbed into the province of Liège.

In World War II, Liège was the site of major fighting during the Battle of the Bulge. There, the Germans orchestrated their final offensive move against the combined Allied armies. Malmedy and Saint-Vith in particular saw intense battles against the Nazis. Malmedy was the site of a Waffen-SS massacre of U.S. Army prisoners of war.

Liège's heavy industry thrived in the 1950s and 1960sbut has been in decline since that time. Nevertheless, Liège remains the last city of Wallonia to maintain a functioning steel industry.

Liège continues to be the economic and cultural capital of Wallonia, with its university, medieval heritage and heavy industry.
