The A1 motorway (Romanian: Autostrada A1) is a partially built motorway in Romania, planned to connect Bucharest with the Banat and Crișana regions in the western part of the country and the rest of Europe. When completed it will be 581 kilometers long and it will span the country on the approximative south-east to north west direction. The motorway starts in the western part of Bucharest and connects the following major cities: Pitești, Sibiu, Deva, Timișoara, Arad, reaching Hungary's M43 motorway near Nădlac. As the motorway is built along the Trans-European Transport Networks Rhine-Danube Corridor the construction receives 85% funding from the European Union. The road is part of the proposed Via Carpatia route.

As of June 2025, the combined length of the opened sections totals 487 kilometers, with all the remaining sections under construction. The parts of the motorway currently in service include the Bucharest – Curtea de Arges section (140 km), the Boița – Holdea section (188 km), and the Margina – Nădlac section (158.8 km).

An additional segment, between Coșevița – Margina (13.5 km), which has several tunnels (2.1 km, in total) along its route is currently under construction

On the Pitești – Sibiu section, two segments were tendered as well: Pitești − Curtea de Argeș (30.4 km, lot 5) and Curtea de Argeș − Tigveni (10.7 km, lot 4), with the latter one awarded for construction in April 2019, and the first segment (Pitești − Curtea de Argeș) in May 2020.

In December 2024, the 16-km segment from Pitești to Curtea de Argeș (lot 5) was opened 8 months in advance.
