Coordinates: 46°14′N 7°39′E / 46.233°N 7.650°E / 46.233; 7.650 The Oberaargau is the region that encompasses the upper watershed of the Aar River in the canton of Bern in Switzerland. On the north, lie the Jura Mountains, and on the south the hills leading to the Emmental

Administratively, the Oberaargau forms a district within the region Emmental-Oberaargau of the canton of Bern. Historically (until 2009), the Oberaargau comprised the two administrative districts of Wangen and Aarwangen.

It lies in the extreme northeast corner of the canton and includes the districts of Aarwangen and Wangen, and part of the district of Trachselwald. It is surrounded by the cantons of Solothurn, Aargau, and Lucerne. It is connected to the rest of the canton of Bern only in the south, where it borders on the Emmenthal.
