Chêne-Bougeries is a municipality in the Canton of Geneva, Switzerland.

Chêne-Bougeries is first mentioned in 1270 as Quercus. In 1801 it was mentioned as Chêne-les-Bougeries.

Chêne-Bougeries was inhabited for most of its history, and neither the Romans nor the Genevans settled there. An important concern for the Genevans was the leprosy hospital that occupied part of the commune; it is only when this illness was defeated around the 16th century that Chêne-Bougeries really started to develop.

During the French Revolution, the territory was occupied by the French. In 1798 the commune was forced to merge with the neighbouring communes of Chêne-Thônex and Chêne-Bourg to create a new entity, the Trois-Chêne. In 1801, however, it was able to regain the autonomous commune status, while Chêne-Thônex and Chêne-Bourg remained unified. In 1816, Chêne-Bougeries, as many of other neighboring communes, became part of a newly Swiss Geneva. Incidentally, Chêne-Thônex was subsequently called Thônex when dissensions led to a new separation with Chêne-Bourg in 1869.

The three communes are still referred today as Trois-Chêne and close ties are still in place. Work on social security, medical assistance, cultural offerings and sport infrastructure, to name a few, are operated in close cooperation between the three.

While it used to be an agricultural commune for most of its history, Chêne-Bougeries, due to its close position to the city of Geneva, became essentially residential, attracting middle to very high revenue families.

Chêne-Bougeries has an area, as of 2009, of 4.13 square kilometers (1.59 sq mi). Of this area, 0.42 km (0.16 sq mi) or 10.2% is used for agricultural purposes, while 0.24 km (0.093 sq mi) or 5.8% is forested. Of the rest of the land, 3.44 km (1.33 sq mi) or 83.3% is settled (buildings or roads), 0.04 km (9.9 acres) or 1.0% is either rivers or lakes.

Of the built up area, housing and buildings made up 66.8% and transportation infrastructure made up 11.6%. while parks, green belts and sports fields made up 3.9%. Out of the forested land, 3.4% of the total land area is heavily forested and 2.4% is covered with orchards or small clusters of trees. Of the agricultural land, 5.1% is used for growing crops and 2.9% is pastures, while 2.2% is used for orchards or vine crops. All the water in the municipality is flowing water.

It consists of the town center and the neighborhoods of Grange-Canal, Malagnou, Le Vallon, La Pommière and Conches as well as the new high-rise developments of La Gradelle and La Montagne.

The municipality of Chêne-Bougeries consists of the sub-sections or villages of Boucle-de-Conches, Conches - La-Petite-Paumière, Conches - Vert-Pré, Bougeries - Clos-du-Velours, Bougeries - Chapeau, Chevillarde - Ermitage, Grange-Canal, Gradelle, Grange-Falquet, Rigaud - Montagne, Chêne-Bougeries - village.
