Oettingen in Bayern (Swabian: Eadi) is a town in the Donau-Ries district, in Swabia, Bavaria, Germany.

The town is located on the river Wörnitz, a tributary of the Danube, and lies on the northern edge of the Nördlinger Ries, a meteorite crater 25 km (16 mi) in diameter.

Unlike nearby Dinkelsbühl, which survived World War II unscathed, Oettingen was severely damaged on 23 February 1945 by an Allied bombing raid, part of Operation Clarion, in which 48 aircraft dropped some 500 bombs on the town, killing 199 persons.

The stone entry level and portal were built in 1431, while the upper floors and the impressive roof framework come from 1480.

The marketplace forms the centre of Oettingen, and the weekly farmers' market takes place here on Fridays.

It accommodated the Latin School which was established in 1563, and served to educate the children of the parish and of the city governors.
