The County of Hanau-Lichtenberg was a territory in the Holy Roman Empire. It emerged between 1456 and 1480 from a part of the County of Hanau and one half of the Barony of Lichtenberg. Following the extinction of the counts of Hanau-Lichtenberg in 1736 it went to Hesse-Darmstadt, minor parts of it to the Hesse-Cassel. Its centre was in the lower Alsace, the capital first Babenhausen, later Buchsweiler.
