Kleinkahl is a community in the Aschaffenburg district in the Regierungsbezirk of Lower Franconia (Unterfranken) in Bavaria, Germany, and a member of the Verwaltungsgemeinschaft (Administrative Community) of Schöllkrippen.
Kleinkahl lies in the Bavarian Lower Main (Bayerischer Untermain).
The community has the following Gemarkungen (traditional rural cadastral areas): Edelbach, Großkahl, Großlaudenbach, Kleinkahl, Kleinlaudenbach, Bamberger Mühle.
Part of the current municipal area lay within the Archbishopric of Mainz and in 1803, on orders given by the Archchancellor of Dalberg, it was secularized. The rest lay within Krombach over which the Counts of Schönborn held sway and passed with mediatization in 1806 to the Principality of Aschaffenburg, with which it passed in 1814 to Bavaria. In the course of administrative reform in Bavaria, the current community came into being with the Gemeindeedikt (“Municipal Edict”) of 1818.
Within the municipal area, there were 1,608 inhabitants in 1970, 1,582 in 1987 and 1,842 in 2000.
