Haut-Rhin

Haut-Rhin (French pronunciation:) is a department in the Grand Estregion, France, bordering both Germany and Switzerland. It is named after the river Rhine. Its name means Upper Rhine. Haut-Rhin is the smaller and less populated of the two departments of the former administrative Alsace region, the other being Bas-Rhin (Lower Rhine), especially after the 1871 cession of the southern territory known since 1922 as the Territoire de Belfort, although it is still rather densely populated compared to the rest of metropolitan France. It had a population of 770,738 in 2023.

On 1 January 2021, the départemental collectivities of Bas-Rhin and Haut-Rhin were merged into the European Collectivity of Alsace.
