Divonne-les-Bains (French pronunciation: [di'vɔn le 'bɛ̃]; Arpitan: Digouona), popularly known simply as Divonne, is a commune in the Ain department in the Auvergne-Rhône-Alpes region in Eastern France.

Divonne-les-Bains is a spa town situated on the border with French-speaking Switzerland, between the foot of the Jura Mountains and Lake Geneva.

Many of its present-day amenities (casino, hippodrome, open air swimming pool, as well as the Lac de Divonne, an artificial lake) were built after 1945.

Divonne-les-Bains used to host a small chamber music festival every summer, centred on its tiny theatre and the Domaine de Divonne.

[3] A number of etymologies have been suggested: From the 2nd century BC the Romans progressively conquered and settled area north of the Alps and west to Lake Geneva.

[5] In the Middle Ages, Divonne's name emerged, as a parish and in the context of its fortified castle and feudal owners.

Sixty years later in 1285, Léonète, the Lady of Gex, alongside her son Pierre, successfully petitioned Amadeus V of Savoy for the return of the castle to their possessions.

Although the French Revolution deprived the aristocracy of much of their assets, Louis de la Forest was able recover some of his land including forests in the Jura, and in 1827 he was named as a hereditary member of the Chambre des pairs (Chamber of Peers) under the constitution of the Bourbon Restoration.

Since 2012 a bus service operates connecting Divonne-les-Bains to the Swiss rail network at Coppet, offering a fast link to Geneva.

The historical economy of the settlement of Divonne and its surroundings in the Pays de Gex was one of agriculture and forestery.

The town is well provided with recreational facilities including a 50 m open-air swimming pool, football pitches, tennis club, golf course, as well as a 3.3 km path around the artificial lake for walkers and cyclists, with exercise points.
