The Nied (pronounced as /de/; in French pronounced as /nje/) is a river in Lorraine, France, and Saarland, Germany. It is a left tributary of the Saar. It is formed where two streams converge: the Nied allemande ("German Nied") and the Nied française ("French Nied"), which join in Condé-Northen.
The "Nied française" is the bigger of the two, with a length of 59km (37miles), and its source is near Morhange. Another town on the "Nied française" is Pange. The other stream, the "Nied allemande" is 58km (36miles) long, with its source in Seingbouse, east of Saint-Avold. Another town on the Nied allemande is Faulquemont.
The Nied itself is 55km (34miles) long, of which 16km (10miles) are in Germany. It flows through Bouzonville, and joins the Saar in Rehlingen-Siersburg.
