The County of Katzenelnbogen (named after Chatti Melibokus) is an immediate state of the Holy Roman Empire.
It exists between 1095 and 1479, when it is inherited by the Landgraves of Hesse.The estate comprises two separate territories.
The main parts are the original Untergrafschaft ("lower county") with its capital at Katzenelnbogen in the Middle Rhine area and the Obergrafschaft ("upper county") south of the Main River around Darmstadt, predecessor of the Landgraviate of Hesse-Darmstadt.
