Hirschhorn is situated at a horseshoe bend of the River Neckar, roughly 19 km east of Heidelberg. The Neckar has dug its way through the wooded hills of the Odenwald here. Hirschhorn stretches along the right bank of the Neckar, i.e. north of the river. Ersheim, Hirschhorn's oldest part, has the distinction, however, of being the only bit of Hesse south of the Neckar. In Hirschhorn, two northern tributaries, the Ulfenbach and the Finkenbach, join to become the Laxbach before flowing into the Neckar.
In the north, Hirschhorn borders on the villages of Heddesbach (Rhein-Neckar-Kreis, Baden-W�rttemberg) and Brombach (part of Eberbach), and on the parish of Rothenberg (Odenwaldkreis). The town of Eberbach (east of Hirschhorn) is also in the Rhein-Neckar-Kreis and therefore in Baden-W�rttemberg. South of Hirschhorn there is the parish of Schoenbrunn (Rhein-Neckar-Kreis); the town of Neckarsteinach is towards the south-west, and to the west of Hirschhorn there is the town of Schoenau (Rhein-Neckar-Kreis), with the forest district of Michelbuch in between, which has its own peculiar status and does not belong to any village or town.
Apart from the town itself, the following villages belong to Hirschhorn:
Langenthal (in the Ulfenbach valley)
Unter-Hainbrunn (in the Finkenbach valley)
Hessisch-Igelsbach (Badisch-Igelsbach is part of Eberbach)
