The farms and land that now make up Wachseldorn were originally part of the "Herrschaft" of Diessbach. In 1356 it was donated to Interlaken Abbey. Around 1399, the area was administered by the Bernese Röthenbach court. In 1528 Bern adopted the new faith of the Protestant Reformation and suppressed Interlaken Abbey. Whatever claims the Abbey still had to Wachseldorn were transferred to Bern after the Abbey was closed. In the following year, Wachseldorn became part of the bailiwick of Signau in the district of Konolfingen. In 1864 it was moved to the Thun District. In 1805 the municipalities of Buchholterberg and Wachseldorn-Gützenschwendi merged to form a single municipality. However, the relationship was short lived and following disagreements, they separated into Wachseldorn and Buchholterberg in 1823.
