DN7 (Romanian: Drumul Naţional 7) is a national road in Romania which links Bucharest with the Banat region, in western Romania, and further to the eastern European capitals Budapest and Belgrade. It is a high-traffic road and the preferred route for trucks. Near Râmnicu Vâlcea the road crosses the Southern Carpathians along the Olt river, through the Valea Oltului touristic region. On its first segment, Bucharest - Piteşti, the road is doubled by the A1 motorway.
