The Moselle has its source roughly 25 kilometres (15 miles) to the southwest of Colmar on the main ridge of the Vosges at Col de Bussang. It flows into the Rhine at Koblenz. Its overall fall of 676 metres (2217 feet) is spread over a total length of 520 kilometres (323 miles).

Its drainage basin covers an area of over 28,286 square kilometres (10,921 square miles). The Moselle, along with its tributaries the Meurthe, Seille, Madon, Orne, Sauer and Saar, belongs to the Rhine basin.

At the border triangle where France, Luxembourg and Germany meet, the Moselle becomes a border river. For a stretch of 36 kilometres (22 miles), the Moselle is an area of joint sovereignty (condominium), administered jointly by the Grand Duchy of Luxembourg and the Federal Republic of Germany.
