As its name suggests, "Ambérieux-en-Dombes" is a part of the Dombes country in Ain. It is located some 10 km east of Villefranche-sur-Saone and 35 km north of Lyon. There are several access roads to the commune: the D904 comes from Savigneux in the west through the heart of the commune and the town and continues east to Lapeyrouse; the D66 road from Saint-Trivier-sur-Moignans in the north passes through the town and continues south to Saint-Jean-de-Thurigneux; the D660 comes from Rancé in the south-west to the town; and the D82 comes from Monthieux in the south-east and continues to Chatillon-sur-Chalaronne in the north-east. All of these roads intersect in or very near the town.
