Hargelsberg is a municipality in the district Linz-Land in the Austrian state of Upper Austria.

The municipality is about 4.5 kilometers from north to south, and about 6.3 km east to west.

Following the Anschluss with Germany on 13 March 1938, the locality was part of Gau Oberdonau" but in 1945 was restored to Bundesland Upper Austria.

Like many municipalities of Upper Austria, Hargelsberg issued Notgeld for collectors in 1920.

Hargelsberg was more prolific than most, with all of its villages and localities issuing special series (Sonderserien) in limited prints.
