The Bucharest Ring Motorway (or the Bucharest Belt Motorway, Romanian: Autostrada Centura București), termed A0, is a motorway ring in construction around the city of Bucharest, the capital of Romania. It is intended to be the outer ring of the existing Bucharest Ring Road.

It is split into two sections: the South Ring Motorway and the North Ring Motorway. It will have a total distance of 100.87 km and will be a motorway connection between the existing A1, A2 and A3 motorways.
