Lichtenstein Castle (German: Burg Lichtenstein) is a high to late medieval hill castle, 380 m above sea level (NN), about six kilometres north of Ebern in the Lower Franconian county of Haßberge in Bavaria. It is located in the municipality of Pfarrweisach.

Of the originally four sub-castles of this great joint-fief or Ganerbenburg only one, the South Castle, is still occupied. The North Castle only survives as ruins. On the site of the now vanished third castle the Protestant Church of the Eternal Flame (Zum Ewigen Licht) was built in the Baroque era. In the southwestern part of the site lie the ruins of a fourth joint-vassal castle seat.
