It is situated on the river Neckar, 15 kilometres (9 miles) north of Rottweil. It historically was and currently is a major center of the German weapons industry.

Oberndorf lies in the Neckar Valley, which is between the Black Forest and the Swabian Jura. The Autobahn A 81 is nearby, with the Oberndorf exit about halfway between Stuttgart and Konstanz. The train line Stuttgart-Zürich-Milan goes directly through Oberndorf as well.

The city of Oberndorf am Neckar is made up of the city proper and the surrounding villages of Altoberndorf, Aistaig, Boll, Bochingen, Beffendorf and Hochmössingen. The formerly independent surrounding villages were put under the administration of Oberndorf during the village and township reforms of Baden-Württemberg in the early 1970s.

Aside from the beautiful Black Forest and wonderful German countryside, Oberndorf offers much to see. It is well known for its annual Karneval celebrations, which remain very traditional. An old historical "freier Markt".
