Oettingen in Bayern is a town in the Donau-Ries district, in Swabia, Bavaria, Germany. It is situated 29 km (18 mi) northwest of Donauwörth, and 14 km (8.7 mi) northeast of Nördlingen.

The House of Oettingen was a high-ranking noble Franconian and Swabian family. It ruled various estates that composed the County of Oettingen between the 12th century and the beginning of the 19th century. In 1674 the house was raised to the rank of prince for the first time. Despite the annexation of their lands following the German mediatisation of 1806, the family retained their titles and still have representatives today.
