Dollnstein is a municipality in the district of Eichstätt in Bavaria in Germany.

The name Dollnstein has its origins in Middle High German "Tollunstein".

Dollnstein was first mentioned in 1007 as a tiny village named Tollenstein.

The castle of Dollnstein was built probably in the mid of the 12th century from the counts von Hirschberg.

From 1440 onwards the village was related to Eichstätt and an administration and judicial authority was located in Dollnstein.
