The A8 motorway (Romanian: Autostrada A8), also known as The Union Motorway (Romanian: Autostrada Unirii) or the East-West Motorway (Romanian: Autostrada Est-Vest) is a planned motorway in Romania, that will cross the Eastern Carpathians to connect the historical regions of Moldavia and Transylvania. It will directly link the cities of Iași and Târgu Mureș. The A8 motorway route is an integral part of the Trans-European Transport (TEN-T) Core Network.

As of May 2025, five sections are under design and construction, while all of the remaining sections are tendered.
