The LGV Rhin-Rhône (French: Ligne à Grande Vitesse; English: high-speed line) is a French high-speed rail line, the first in France to be presented as an inter-regional route rather than a link from the provinces to Paris, though it actually is used by some trains to/from Paris.

The completed section, referred to as the first phase of the eastern branch, is 140 km long, running from Villers-les-Pots, Côte-d'Or
