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

[3] The scattered villages that make up Fahrni were originally part of the Kyburg Herrschaft of Heimberg.

In 1384 they were forced to sell most of their lands, including Fahrni, to the city of Bern.

[3] Fahrni has always been part of the parish of Steffisburg, though a filial church was built in 1951 in Rachholtern.

The Obere Mürggen neighborhood was built to house the slowly growing population, but much of the community is unchanged.

It includes the village known as Dörfli and the hamlets of Rachholtern, Lueg, Äschlisbühl, Bach and Embergboden as well as scattered individual farm houses.
