DN5 (Template:Lang-ro) is an important national road in Romania which links Bucharest with the southern country border with Bulgaria by the Giurgiu Russe Friendship Bridge.

DN5 has been designated as a priority express road, being upgraded between 2006 and 2009. Between Bucharest and Giurgiu, for the most part, it is a non-grade separated dual carriageway with no emergency lane, with entrances and exits from adjacent roads using roundabouts. Some segments (such as the Adunații-Copăceni bypass) are constructed to full motorway standard (dual carriageway, full grade-separation, wide median separation).

It is one of the most transited roads in southern Romania, serving as the main connection between Romania's capital, Bulgaria and the rest of Southeast Europe.
