The Duinger Berg lies in the western part of the Leine Uplands, a northern section of the Lower Saxon Hills.

It is situated in the triangle formed by the settlements of Eime, Alfeld and Duingen and also lies between Deinsen and Lübbrechtsen to the north, Rott, Hoyershausen and Lütgenholzen to the east, Brunkensen to the southeast, Coppengrave to the south, Duingen to the southwest and Weenzen and Marienhagen to the northwest.

Northwest of the Duinger Berg is the ridge of the Thüster Berg, to the east is the Külf, southeast the Reuberg and west the knife-edge of the Ith, part of which lies within the Weser Uplands-Schaumburg-Hamelin Nature Park.

The valley of the Glene, a southwestern tributary of the Leine leads to the Reuberg.

One hiking trail runs over the crest of the ridge from Marienhagen to Brunkensen.
