Saint-Cyran-du-Jambot (French pronunciation: [sɛ̃ siʁɑ̃ dy ʒɑ̃bo]) is a commune in the Indre department in central France.

Saint-Cyran's origins lie with a monastic foundation founded by Saint Sigiramnus (Cyran) in the 7th century.

[3] The foundation was first known as Saint-Pierre de Longoret (Longoretum, Lonrey) but was later named after its founder.

[3] In the 17th century, Jean du Vergier de Hauranne, known as the Abbé de Saint-Cyran, served as abbot of this monastery.

He was succeeded by his nephew Martin de Barcos.
