Saint-Rhémy-en-Bosses (French: [sɛ̃ ʁemi ɑ̃ bɔs] ⓘ; Valdôtain: Sèn Rémi eun Boursa) is a village and comune in the Aosta Valley region in the north-western Italy.

Its Latin name is Endracinum: in Roman times an important mansio stood on the valley to control the road, since the village was located in a strategic point for trade through the Alps.

According to tradition, during the Burgundy domination Guntram, passing through the valley, was baptized by Saint Remigius, Archbishop of Reims, in 496 AD, thus giving his name to the town.

Saint-Rhémy-en-Bosses is mentioned in the travelogue of Sigeric of Canterbury who, around 990, went to Rome to receive the Pallium from the hands of Pope John XV; this route would have been called Via Francigena, in the following centuries.

In particular, the locality represented the XLVIII stage (submansio), and was defined by the Archbishop of Canterbury Sce Remei.
