Aldersbach (Central Bavarian: Oidaschbo) is a municipality in the district of Passau in Bavaria in Germany. The former Cistercian Aldersbach Abbey, of which the Baroque church remains, is located in the village. There is also a brewery with museum. Aldersbach has around 4,500 inhabitants.

Aldersbach is located in the Donau-Wald region in the Vils valley, some ten kilometers south west of Vilshofen an der Donau, 30 km west of Passau, 25 km north of Pfarrkirchen and 15 km south of Osterhofen. A stream, the Aldersbach (Bach = stream), flows through the town. Not least in the context of tourism, the region bounded by Aldersbach and Fürstenzell is often referred to as Klosterwinkel (Abbey Corner).

The community of Aldersbach is made up of 52 parishes:^[3]

These are assigned to the Gemarkungen (sub-districts) of Pörndorf, Walchsing, Aldersbach and Haidenburg.

• Johanniskirchen (Landkreis Rottal-Inn)
• Roßbach (Landkreis Rottal-Inn)
• Osterhofen (Landkreis Deggendorf)
• Künzing (Landkreis Deggendorf)
• Vilshofen an der Donau (Landkreis Passau)
• Aidenbach (Landkreis Passau)

A settlement called Aldarespah is first mentioned in the mid-8th century in a codex belonging to Mondsee Abbey. The ostensible earliest mention of a church in Aldersbach dating from this period resulted from the misinterpretation of note from the early 14th century to be found in the earliest book of accounts of Aldersbach Abbey. 1120 saw the establishment of the first abbey in Aldersbach (St. Peter), founded by the religious order of the Augustinian Canons. By c. 1140 the name Alderbach was in common use and a Latinized form, Adalogeriopagus, appears in records from the early 16th century. The name derives from the name of a person, Althar or Aldar and the Old High German word for a stream: pah or pach. Aldersbach fell under the financial stewardship of Landshut and the jurisdiction of Vilshofen district court in the Electorate of Bavaria. Aldersbach Abbey had its own limited jurisdiction as a Hofmark, before being suppressed in 1803 during the secularization of Bavaria. In 1806 the local Weng and Bernhardsberg churches were sold and demolished. The community of Aldersbach was created by the Community Edict of 1818 in the course of administrative reforms in Bavaria.

Enforced membership of the administrative community of Aidenbach was lifted in 1980.

The parish of Walchsing is first mentioned in records in 1100. Haidenburg hosted a manor house that originally belonged to the House of Harbach, had been acquired by Aldersbach Abbey in 1737 and following secularization in 1818 was purchased by Johann Adam Freiherr von Aretin in 1811. As part of administrative reforms in Bavaria, the Community Edict of 1818 led to the formation of the parishes of Pörndorf, Haidenburg and Walchsing, which were incorporated into Aldersbach in 1972.

The previously separate community of Walchsing and parts of the dissolved community of Haidenburg were incorporated on January 1, 1972, while Pörndorf (District of Eggenfelden) was incorporated on July 1, 1972.^[4]
