Moselle is the most populous department in Lorraine, in the east of France, and is named after the river Moselle, a tributary of the Rhine, which flows through the western part of the department. Inhabitants of the department are known as Mosellans.

Over the past twenty years the Conseil departemental de la Moselle has encouraged the development of tourism in the department. The creation of more hotels, camp sites, hiking trails, bicycle paths, and other tourist services have significantly increased the number of tourists in Moselle.

The Conseil departemental de la Moselle created an "Organ Trail" to display a number of the department's 650 organs, many of which were built in the area and have historic significance. The oldest organ in the department dates is in the cathedral Saint-Étienne de Metz and dates from 1537. In the 19th century, Moselle had 17 operational organ factories, although only five exist in the present day.

Moselle has numerous chateaux, manors, and fortified manors, dating largely from the 17th and 18th centuries, many of which are partially destroyed.
