Oberhofen am Thunersee is a municipality in the administrative district of Thun in the canton of Bern in Switzerland.
Historically Oberhofen was primarily an agricultural community (mainly vinticulture) until the late 19th century. Today it is a rather affluent residential community, privileged by geography. The hill slopes to the lake toward south-west, giving both much sunlight, and a spectacular view to the glacier covered high alpine peaks of the Bernse Alps across the lake.
The dominant feature of the village is the lakeside castle of Oberhofen, dating back to the Middle Ages, but constantly changed and updated throughout the ages. The castle today houses a division of the Historic Museum of Bern, and has a spectacular formal lakeside garden in the English style with many rare specimen trees.
