The A3 motorway (Romanian: Autostrada A3) is a partially built motorway in Romania, planned to connect Bucharest with the Transylvania region and the north-western part of the country. It will be 596 km long and will run along the route: Ploiești, Brașov, Făgăraș, Sighișoara, Târgu Mureș, Cluj-Napoca, Zalău and Oradea, connecting with Hungary's M4 motorway near Borș.

As of September 2023, there are roughly 185 km (115 mi) in service: the Bucharest – Ploiești motorway (62.5 km), the Râșnov – Cristian segment (6.3 km), the Târgu Mureș – Chețani segment (36.1 km), the Câmpia Turzii – Nădășelu segment (61.2 km) and the Biharia – Borș segment (5.4 km).

In January 2015, the motorway section between Târgu Mureș – Câmpia Turzii was awarded for construction. It was divided into two larger segments, with a total of five lots, which sum up 51.8 km. By December 2021, all segments have been opened to traffic, with the exception of Chețani − Câmpia Turzii (15.7 km), of which contract was terminated in March that year.

Additional works on the Nădășelu – Borș section (approx. 157 km, in total) were auctioned between 2018 and 2019, with contracts awarded for the Biharia − Borș segment (5.4 km, near the border with Hungary) in December 2018, the Chiribiș − Biharia segment (28.6 km) in June 2020, and the Zimbor – Poarta Sălajului segment (12.2 km) on the same month. Several other segments are still pending to be awarded.

Furthermore, on the Comarnic − Brașov section (58.0 km), the 5.2 km segment between Comarnic South – Comarnic North has been re-tendered in August 2020.
