Hüttlingen lies on the eastern edge of the Swabian Alb at 400 to 503 meters above sea level at the Kocher river bend, about seven kilometers from the district town of Aalen.

The municipality borders Neuler to the northwest, Rainau to the northeast, Abtsgmünd to the west, and the district town of Aalen to the south.

The municipality of Hüttlingen includes the village of Hüttlingen, the hamlets of Albanuskling, Mittellengenfeld, Niederalfingen, Oberlengenfeld, Seitsberg, Sulzdorf, the farms of Halmeshof, Lachenschafhaus, Obersiegenbühl, Unterlengenfeld and Untersiegenbühl, and the houses Fuchshäusle, Haldenschafhaus, Straubenmühle and Zanken, as well as the deserted villages of Aushof, Haselhof and Rotschafhaus.

[3] The Upper Germanic-Raetian Limes (ORL), a section of the former outer border of the Roman Empire, ran through Hüttlingen's district and made a bend in a field across from the Wasserstall residential area on the Hochfeld path.

In the High Middle Ages, the Hüttlingen area lay in the northern border region of the Swabian tribal duchy.

Marienburg in the district of Niederalfingen is now used as a youth education center, recreational facility and school camp.

The Hüttlingen local group of the Swabian Alb Association, founded in 1896, was awarded the Eichendorff Plaque in 1996.

Trains on the Aalen–Crailsheim (Obere Jagstbahn) and Aalen–Donauwörth (Riesbahn) lines stop at the Goldshöfe station, about 2 km from the center of Hüttlingen.
