Parco fluviale del Tevere, Protected regional park along Tiber River in Perugia and Terni, Italy.

Parco fluviale del Tevere is a protected regional park stretching along a major section of the Tiber River, linking several municipalities across two provinces. The land includes forested areas, meadows, steep banks, and river curves where woodland, open grassland, and exposed rocky slopes meet the water.

The park was established as a WWF protected area in 1990, then formally instituted by regional law no. 9 of 3 March 1995 to protect and enhance part of the Tiber basin. It covers about 7,295 hectares along roughly 50 km of river, from Montemolino near Todi to Lake Alviano, including the lakes of Alviano and Corbara. Archaeological sites lie in the municipalities of Baschi and Orvieto.

The park's name comes from the Tiber, which springs on Monte Fumaiolo and runs through Umbria. The WWF oasis at Lago di Alviano is a stopover for migratory birds, and the lakes of Alviano and Corbara draw birdwatchers. Vineyards and olive groves cover the hillsides around Todi and Monte Castello di Vibio.

The park stretches about 50 km from Montemolino, a hamlet of Monte Castello di Vibio near Todi, to Lake Alviano, taking in the lakes of Alviano and Corbara. Lake Alviano, managed by WWF, is a stopover for migratory birds, so bring binoculars. Access is spread across the municipalities of Alviano, Baschi, Guardea, Monte Castello di Vibio, Montecchio, Orvieto and Todi.

The park's two lakes, Alviano and Corbara, are the feature visitors most often miss: Alviano, managed by WWF, is a stopping point for migratory birds, where coots, kingfishers, peregrine falcons and herons can be watched. The park runs about 50 km from Montemolino, a hamlet of Monte Castello di Vibio near Todi, to Lake Alviano.
