La Bâtie-Montgascon (French pronunciation: [la bati mɔ̃ɡaskɔ̃]) is a commune in the Isère department in the Auvergne-Rhône-Alpes region of south-eastern France.

The inhabitants of the commune are known as Batiolans or Batiolanes.

La Bâtie-Montgascon is located some 20 km east by south-east of Bourgoin-Jallieu and 25 km west of La Motte-Servolex. Access to the commune is by the D1516 road from La Tour-du-Pin in the west which passes through the north of the commune and the village before continuing east to Aoste. The D1075 comes from Veyrins-Thuellin in the north and passes through the hamlet of Evrieu in the commune before continuing south-east to Les Abrets. The A43 autoroute passes through the south of the commune from west to east but has no exit in the commune. The nearest exit is Exit  10  east of the commune at Chimilin. Apart from the main village there are the hamlets of Évrieu, Avolin, Trévignieux, and Boutière. The commune is almost all farmland with a few small forests and small lakes.

The Bourbre forms the southern border of the commune as it flows west to eventually join the Rhône near Chavanoz.

La Bâtie-Montgascon appears as La Batie Mongafco on the 1750 Cassini Map and as la Batie on the 1790 version.
