Lorraine is one of the 26 régions of France. The administrative region has two cities of equal importance, Metz and Nancy. Metz is considered to be the official capital since that is where the regional parliament is situated. The region's name is derived from the medieval Lotharingia.

The region consists of four departments: Meurthe-et-Moselle, Meuse, Moselle and Vosges and contains 2,337 communes.
