The Regional Council of Lorraine (French: Conseil régional de Lorraine, German: Regionalrat von Lothringen) was the deliberative assembly of the former French region of Lorraine until December 31, 2015, following the region's incorporation with Champagne-Ardenne and Alsace to form the new Grand Est region.

It has 73 members and sits in the former abbey of Saint-Clément, in the Pontiffroy district of Metz.

The Hôtel de Région is one of the many sites occupied by the Regional Council: boulevard de Trèves (recently renovated military buildings), Sainte-Barbe and Blida for Metz (there is also a site in Nancy).

Its last president was Jean-Pierre Masseret (PS), elected on March 28, 2004.

[1][2] The Regional Council of Lorraine was also a member of the cross-border inter-regional cooperation called Grande Région, or "SaarLorLux".
