The Saar (//, also US: //, German: [zaːɐ̯] (listen); French: Sarre [saʁ]) is a river in northeastern France and western Germany, and a right tributary of the Moselle. It rises in the Vosges mountains on the border of Alsace and Lorraine and flows northwards into the Moselle near Trier. It has two headstreams (the Sarre Rouge and Sarre Blanche, which join in Lorquin), that both start near Mont Donon, the highest peak of the northern Vosges. After 246 kilometres (153 mi) (129 kilometres in France and on the French-German border, and 117 kilometres in Germany) the Saar flows into the Moselle at Konz (Rhineland-Palatinate) between Trier and the Luxembourg border. It has a catchment area of 7,431 square kilometres (2,869 sq mi).

On the banks of the Saar is the UNESCO-World Heritage Site Völklinger Hütte. At Mettlach the Saar passes the well-known Saar loop. The lower Saar in Rhineland-Palatinate is a winegrowing region of some importance, producing mostly Riesling. Until the early 20th century, much more wine was grown on the banks of the Saar, reaching much further up from the mouth of the river, up to Saarbrücken. Only in the early 21st century have some enterprising farmers from the Saarland area started experimenting with winegrowing again.
The name Saar stems from the Celtic word sara (streaming water), and the Roman name of the river, saravus.
