The Aniene River (in Latin: Anio; formerly called the Teverone) is a 99-kilometre (62 mi) river in Lazio, Italy. It originates in the mountains at Trevi nel Lazio and flows westward past Subiaco, Vicovaro, and Tivoli into the Tiber. In antiquity, most of the Roman aqueducts had their sources either at the Aniene or the streams flowing into it.

Notable historic bridges across the river include the Ponte Nomentano, Ponte Salario and Ponte di San Francesco, all of which were originally fortified with towers. The Roman-built Subiaco Dam at the town of the same name is considered the highest ancient dam and remained in use until its destruction in 1305.[1] [2] [3]
