Kaisheim is a municipality in the district of Donau-Ries in Bavaria in Germany.

Kaisheim was the local High Reeve's office and belonged to Kaisheim Abbey, an Imperial Abbey.

The Abbey was founded in 1133 by Graf Heinrich III von Lechsgemünd and his wife Liutgard.

Since the German Mediatisation of 1803, Kaisheim has belonged to Bavaria and from the Bavarian reform edict of 1818 the present day community arose.

The Latin title given to the town was "Caesarea" from "Kaisersheim".
