Ludiès (French pronunciation: [lydjɛs]; Occitan: Ludièrs) is a commune in the Ariège department in southwestern France.

The detailed structure of the outcropping layers is described in sheet "n°1057 - Pamiers" about the harmonized geological map at approximately about 1/50,000th of the department of Ariège.

[4][5] The cadastral area of the town published by Insee, which serves as a reference in all statistics, is 1.87 km (1.16 mi).

Thus, the Rigaud de Vaudreuil in particular, apart from their seigneury of Trémoulet and a quarter of that of Carlaret, were also half co-lords of Ludiès and Saint-Amadou, it being understood that the other half belonged in joint possession to the King of France, and the other to the Abbey of Saint-Antonin in Pamiers, under the condition of continuing to honor the abbey with a live sparrowhawk on Saint-Antonin's Day.

[11] Since February 2005, the mayor has been Danielle Bouché, of the Divers gauche party, characteristic of central Occitanie's socialist tendencies.
