Saint-Yrieix-le-Déjalat (French pronunciation: [sɛ̃.t‿iʁjɛ lə deʒala]; Occitan: Sent Iries lo Desjalat) is a commune in the Corrèze department in central France.

Saint Yrieix (Aredius), who died in 591, was a contemporary of Gregory of Tours.

In Attanum he founded a monastery that is the source of the walled city of Saint-Yrieix-la-Perche.

He also built churches in honor of various saints he had gone for the relics.

Under the French Revolution, to follow a decree of the Convention, the town changed its name to Yrieix le Déjalat.
