Lichtenstein is a municipality in the Tübingen administrative region in Baden-Württemberg, Germany. It lies at the foot of the Swabian Jura (plateau).

The municipality of Lichtenstein was created on 1 January 1975 by the merger of Honau, Holzelfingen [de], and Unterhausen (which had in 1930 merged with Oberhausen). By the agreement made before this merger, Unterhausen changed its name to Lichtenstein, after the famous Lichtenstein Castle above the town. The towns of the municipality expanded substantially from 1975 to 1990 thanks to tourism. Lichtenstein expanded the most, first purchasing an old industrial site in 1979 to turn it into a new town center.

The municipality (Gemeinde) of Lichtenstein covers 34.24 square kilometres (13.22 sq mi) of the Reutlingen district, in the state of the Federal Republic of Germany.
