Thierhaupten is a market town in south-central Germany in the district of Augsburg (district) in the Swabia administrative region of Bavaria, and is located at the Lech Valley.

The Kühberg (499 m NN) ("cow hill") in the village district of Neukirchen is the highest elevation of Thierhaupten.

The Kreuzberg (479 m NN) ("cross hill") dominates the Thierhaupten town itself.

After a legend, in the year 750 Tassilo III, Duke of Bavaria (Agilolfings dynasty) lost his way in the woods around Thierhaupten and swore to God to build a monastery (Thierhaupten Abbey) at the place of his rescue.

The remaining buildings gradually fell into disrepair, but were bought by the Thierhaupten market town administration in 1983 and renovated.
