Beaucroissant (French pronunciation: [bokʁwasɑ̃]) is a commune in the Isère department in the Auvergne-Rhône-Alpes region of south-eastern France.^[3]

The inhabitants of the commune are known as Manants or Manantes.^[4]

Beaucroissant is located some 32 km south by south-east of Bourgoin-Jallieu and 25 km north-west of Grenoble. Access to the commune is by the D1085 road from La Frette in the north-west which passes through the commune just north of the village and continues east to Moirans. The D519 comes from Izeaux in the west and passes through the commune turning north to join the A48 autoroute at Exit  9 . A railway from Le Grand-Lemps passes through the commune with a station in the village and continues north-east to Rives. Apart from the village there is the hamlet of Le Mollard. Apart from the large urban area of the village and Le Mollard the commune is mainly farmland.^[5][6]

Beaucroissant appears as Beaucroißant on the 1750 Cassini Map^[7] and as Beaucroissant on the 1790 version.^[8]

The commune is famous for its annual fair which has continued since 1219 due to the pilgrimage of Our Lady of Parménie.^[9] The history of the village and the Fair is linked with the Parménie hill that dominates the commune with its 749-metre altitude.

The origin of the Beaucroissant fair dates back to 14 September 1219 when the Saint Laurent lake (above the Bourg d'Oisans) overflowed causing a terrible flood that inundated Grenoble and had many victims. Starting from 14 September 1220, organised by the bishop of Grenoble, survivors commemorated this event with a pilgrimage to Parménie. They were so numerous that a village was needed to accommodate them. The assembly attracted many merchants so the Fair of Beaucroissant was begun.

The official status of the blazon remains to be determined. Blazon: Party per bend sinister, at 1 Azure a cow's head caboshed Argent; at 2 Vert a horse's head Argent; in chief Gules, a crescent Argent from which spread nine rays the same.
