Uebeschi is a municipality in the administrative district of Thun in the Canton of Bern in Switzerland .

Uebeschi is first mentioned in 1233 as Ibisshe.

The oldest traces of settlements in the area come from scattered neolithic and Bronze Age artifacts. Part of a wall, ceramic floor tiles, a stone path and coins have been found from the Roman era, indicating that there was a small settlement in the area.

During the Middle Ages the village was part of the court and parish of Thierachern in the Strättligen Herrschaft. While there is a Ministerialis (unfree knights in the service of a feudal overlord) family von Uebeschi, there are no records that connect them to the village.
