DN3 () is a national road in Romania, originally linking Bucharest and Constanța via Călărași, but no longer serving this purpose for more than four decades. The road is not complete, in the sense of having a gap across the Danube between Călărași and Ostrov. The gap is covered by ferry-boats operated by two private companies every 30–35 minutes during the day and every 45–90 minutes during the night.

When designated as a trunk route, in the early 1960s, this was the shortest road between Bucharest and Constanta, as, at that time, there were no road bridges connecting Dobrudja with the rest of Romania (the King Carol I Bridge at Cernavodă being rail only).
