Haut-Rhin is a department in the Grand Est region of 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 the Bas-Rhin. Especially after the 1871 cession of the southern territory known since 1922 as Territoire de Belfort, although it is still densely populated compared to the rest of metropolitan France.
On 1 January 2021, the departments of Bas-Rhin and Haut-Rhin have been merged into the European Collectivity of Alsace.
