The Taro (Latin Tarus) is a river in Emilia-Romagna, in northern Italy. It is a tributary of the Po and is 126 kilometres long. It flows almost entirely in the province of Parma, west of the city Parma. The Taro flows into the Po near Gramignazzo, a frazione of the comune of Sissa, north of Parma.
The Val di Taro, or Taro valley, the drainage basin of the river, occupies an area of 2,026 square kilometres. The principal affluents of the Taro are the Ceno, Recchio and Stirone; others are the Gotra and Tarodine. Both the Taro and the Ceno rise on Monte Penna, elevation 1,735 metres, in the Apennine Mountains on the border between the provinces of Genoa and Parma.
