Alsace is a cultural region and a territorial collectivity in the Grand Est administrative region of northeastern France, on the west bank of the upper Rhine, next to Germany and Switzerland. In January 2021, it had a population of 1,919,745. Alsatian culture is characterized by a blend of German and French influences.

Until 1871, Alsace included the area now known as the Territoire de Belfort , which formed its southernmost part. From 1982 to 2016, Alsace was the smallest administrative région in metropolitan France, consisting of the Bas-Rhin and Haut-Rhin departments. Territorial reform passed by the French Parliament in 2014 resulted in the merger of the Alsace administrative region with Champagne-Ardenne and Lorraine to form Grand Est.
