Kleinheubach is a market community in the Miltenberg district in the Regierungsbezirk of Lower Franconia (Unterfranken) in Bavaria, Germany and the seat of the like-named Verwaltungsgemeinschaft (municipal association).

Kleinheubach borders on (from the north, clockwise): Grossheubach, Miltenberg, Rüdenau, Michelstadt (in Hesse) and Laudenbach.

At the time of sale, the Princes had to promise that this Protestant place would be allowed unhindered to keep the Augsburg Confession even under their Catholic rule.

They had a stately palace built by Johann Dientzenhofer on the site of the former castle, which is still owned by the family today.

The market community’s seal is known from imprints between 1810 and 1840, and shows the same composition, although the lion is in some cases on flat ground rather than the “mount of three” (or Dreiberg, as this device is called in German heraldry).
