Lozère (French pronunciation: [lɔzɛʁ] ⓘ; Occitan: Losera [luˈzeɾɔ]) is a landlocked department in the region of Occitanie in Southern France, located near the Massif Central, bounded to the northeast by Haute-Loire, to the east by Ardèche, to the south by Gard, to the west by Aveyron, and the northwest by Cantal.

In the north-west, the basalt plateau of Aubrac rises between 1,000 and 1,450 m (3,280 and 4,760 ft), with a cold humid climate influenced by the Atlantic.

The Causses are a series of very dry limestone plateaus in the south-west, and the south-east contains the Cévennes, which include the highest point in the department, the granite Mont Lozère at 1,702 m (5,584 ft).

Since the end of the 19th century the department has seen its population decline due to negative migration, the last fifteen years have nevertheless shown a new upward trend.

The reasons given for this trend are the quality of the living environment, the improvement of the road transport and communication network and to a lesser extent heliotropism.

appear as small living areas but are unable to attract young people, including the exodus towards neighboring metropolises (Clermont-Ferrand in the north, Montpellier and Nîmes to the south) is increasingly important.

The region has one of the lowest rates of unemployment in France, which may be attributed to the enforced long-standing tradition whereby young people emigrate to cities such as Lyon, Marseille, and Montpellier when they reach working age.
