Hoppegarten is located close to the eastern suburbs of Berlin (Mahlsdorf, in the borough of Marzahn-Hellersdorf).
As a result of the building of two more developing areas (Hellersdorf and Kaulsdorf) the number of inhabitants increased so that the borough Hellersdorf was founded out of the three districts Hellersdorf, Kaulsdorf and Mahlsdorf on 1 June 1986.
