Saint-Junien (French pronunciation: [sɛ̃ ʒynjɛ̃]; Occitan: Sent Junian) is a commune in the Haute-Vienne department in the Nouvelle-Aquitaine region in west-central France.

The history of Saint-Junien began in AD 500, when an ascetic of Hungarian origin, Saint Amand, chose to live on the north bank of the Vienne River at a place called Comodoliac.

At this time, Junian (Junien), originally from the north of France and son of a Count of Cambrai, left his family at the age of 15 and became a disciple of Saint Amand.

Saint-Junien is a city of strong communist tradition, marked by the municipality of Roland Mazoin, (mayor from 1965 to 2001), now headed by Pierre Allard, member of the Alternative Democracy Socialism [fr] (locally implanted party born of a split with the PCF).

This peculiarity is largely inherited from the importance of the industrial sector of glove making, especially in the nineteenth and twentieth centuries, like Limoges.
