Sayn-Wittgenstein-Hohenstein was a county between Hesse-Darmstadt and Westphalia. It was formed by the 1657 partition of Sayn-Wittgenstein-Wittgenstein and raised from a county to a principality of the Holy Roman Empire in 1801. It belonged from 1806 to 1815 to the Grand Duchy of Hesse and after 1816 to Prussia. The capital was Laasphe.
