Onans is a commune in the Doubs department in the Bourgogne-Franche-Comté region in north-central France with a population of 344 as of 1 January 2018.


Onans is situated at 363 m, seven kilometres north-northeast of L’Isle-sur-le-Doubs and about 14 kilometres west of the town of Montbéliard (as the crow flies). The village extends in the valley of the Ruisseau d’Onans in the hilly landscape north of the Doubs valley, at the eastern foot of the Mont de Pierre Trouée.

The area of the 14.17 km² commune covers a section of the hilly landscape to the north of the Doubs valley. The area is crossed from north to south by the valley basin of the Ruisseau d’Onans. South of the village, the stream seeps away. This hollow is flanked to the west by the ridge of Mont de Pierre Trouée(469 m). Further to the southwest, the commune floor extends across the basin of Geney to the Mont du Bois des Roches(463 m) and the Mont de Bellevoie (459m). To the east of Onans, the municipal territory extends to the plateaus of Bois de la Craie, Bois des Tronchots, La Broche and Les Chauselles. Here the highest elevation of Onans is reached with 481 m. The whole area shows a loose structure of arable land, meadows and forest. With the exception of the Ruisseau d’Onans, there is no surface watercourse, because the rainwater seeps into the karstified subsoil of the limestone plateaus.

Neighbouring communes of Onans are Marvelise and Gémonval to the north, Arcey, Montenois and Faimbe to the east, Médière and Étrappe to the south and Geney and Courchaton to the west.


A church in Onans is mentioned in documents as early as 1199. In the Middle Ages, Onans belonged to the lordship of Granges, which came under the sovereignty of the Counts of Montbéliard in the 14th century. Together with Franche-Comté, the village became part of France at the Peace of Nijmegen in 1678. Today, Onans is part of the Deux Vallées Vertes commune.

With 344 inhabitants (as of 1 January 2018), Onans is one of the small communes of the Doubs department. After a significant decline in the first half of the 20th century (437 people in 1886), the population has been growing since the mid-1970s.

Economy and infrastructure

Until well into the 20th century, Onans was a village dominated by agriculture (arable farming, fruit growing and livestock breeding) and forestry. In addition, there are now some local small businesses. In the meantime, the village has also become a residential community. Many employees commute to work in the larger towns in the surrounding area.

The village is located off the main thoroughfares on a departmental road leading from Longevelle-sur-Doubs to Crevans. The nearest access to the A36 motorway is approximately 15 kilometres away. Other road connections exist with Geney and Arcey.
