The Trebbia (stressed Trèbbia; Latin: Trebia) is a river predominantly of Liguria and Emilia Romagna in northern Italy. It is one of the four main right-bank tributaries of the river Po, the other three being the Tanaro, the Secchia and the Panaro.

Along its eastern banks in 218 BC was fought one of the battles of the Second Punic War: the Battle of Trebbia, where Hannibal defeated a Roman consular army.

The 1,150-square-kilometre (440 sq mi) drainage basin is divided among Emilia Romagna, 770 square kilometres (300 sq mi), Liguria, 349 square kilometres (135 sq mi), and Lombardy, 31 square kilometres (12 sq mi). Its principal tributaries are the torrents Aveto and Perino (from the right) and the torrent Boreca (from the left).^[2]
