The Arch of Augustus is a monument in the city of Aosta, northern Italy.
It was erected in 25 BC on the occasion of the Roman victory over the Salassi and was the work of Aulus Terentius Varro Murena.
It is located at the end of the decumanus maximus, a little distance from the Bourg Saint-Ours and from the eastern entrance of the city wall.
