The Tordino is a river flowing in the province of Teramo, in the Abruzzo region of central Italy. In Roman times it may have been known as "Batinus".
The source of the Tordino is located between Monte Gorzano and Pelone, in the Monti della Laga subchain of the Apennines. After a course of 58 kilometres (36 miles), it flows into the Adriatic Sea. The river initially flows in a torrent to the east through the Gran Sasso National Park, then directs to the north around Mount Bilanciere before flowing in a south-easterly direction. The river curves northward near Torricella Sicura and flows past Teramo. The river flows northeast past San Nicolò a Tordino and Castellalto before flowing into the Adriatic Sea near Giulianova and Cologna Spiaggia.
