Thierachern is a municipality in the administrative district of Thun in the canton of Bern in Switzerland.

The remains of a Roman era settlement and graves were discovered under the village church.

Additional Roman or early medieval stone lined cists were found near Egg.

Other graves, of an indeterminate age, have been found in Oberen Hasliholz, by Halterain and by Wahlen.

The current church dates to 1706-08 when Abraham Dünz the Younger rebuilt the old building.

When the Strättligen family died out in 1349, the village was inherited and sold to several lords over the following centuries.

They sold it to Bern in 1607 and the village became part of the Bernese Thun District.

In 1841 the village sold a large Allmend or common field (about 23% of the total land area) to the Swiss Army for a training ground for the barracks at Thun.
