Vielha e Mijaran (Occitan pronunciation: [ˈbjeʎa e miʒaˈɾan]) is a municipality in central Aran, Catalonia, Spain.

Mijaran literally means "Middle Aran" in Aranese, as the inhabited part of the municipality is situated in the valley of the Garonne (Garona).

The municipality is linked to France and to the rest of Catalonia (via the Vielha tunnel) by the N-230 road.

The C-28 (old name: C-142) road continues up the valley to Naut Aran, and on over the Port de la Bonaigua (2,072 m, 6,798 ft) to the comarca of Pallars Sobirà.

This road, the higher stretches of which are impassable in winter, was the only route between the Aran valley and the rest of Spain before the opening of the Vielha tunnel in 1948.
