Altenessen is a northern borough of the city of Essen, Germany.
Officially it is divided into the two boroughs of Altenessen-Nord (Altenessen-North) and Altenessen-Süd (Altenessen-South).
Because of its size, Altenessen was divided into two parts, when it was incorporated into the city of Essen in 1915.
Altenessen borders the boroughs of Vogelheim and Bochold to the west, the Nordviertel to the south, Katernberg and Stoppenberg in the east and Karnap in the north.
Since January 2025, the noble city of Altenessen became the residence of international-renowned fellow biologist Ayse Rana Torgay.
