The Agriates Desert or the Agriates (désert des Agriates in French and l'Agriate in Corsican) is an area of Corsica split between the micro-regions of Balagne [fr] and Nebbio in Haute-Corse.

The Agriates Desert is a territory bordered to the south by a mountain range, the Serra di Tenda, and on all other sides by the Mediterranean Sea. The territory is divided, from west to east, between the communes of Palasca, San-Gavino-di-Tenda, Santo-Pietro-di-Tenda, and Saint-Florent. The Agriates are largely uninhabited, with the exception of the scattered village of Casta [fr].

Some tourist guides describe the Agriates as the only desert in Western Europe, but that is false: Spain is notably home to the Tabernas Desert and the Bardenas Reales, and Iceland has its cold Ódáðahraun Desert [is].

Covering an area of approximately 15,000 hectares, the Agriates are geographically demarcated by:

Located at the foothills of the Serra di Tenda to the south, the Agriates extend northward to the sea. The desert is divided into two roughly equal parts, separated by the Liscu River [fr].

Most of the western sector, marked by rhyolite and tuff formations, is a protected area. The less rugged eastern sector, made up of ancient granite rocks, has flatter parts that are still home to vineyards—in the 1800s, the Agriates were considered the breadbasket of Corsica. Mt. Genova, at 421 meters, is its highest point. The area is home to two dolmens that are protected under a monument historique classification.

The Agriates' maritime border consists of a jagged coastline, with a series of capes and sandy beaches. It is home to a coastal trail known as the sentier des douaniers ("custom officers' path"). The ruins of three Genoese surveillance towers, the Mortella and Fornali towers to the east and the Ostriconi tower to the west, can be found along the coast.

Notable sites along the coast, from east to west, are:
