Rotenhan Castle (German: Burg Rotenhan) is a castle ruin about two kilometres north of the village of Eyrichshof in Lower Franconia in the south German state of Bavaria. Eyrichshof lies within the borough of Ebern in the district of Haßberge. The castle is the ancestral home (Stammsitz) of the House of Rotenhan, a family of imperial knights.

The Rotenhan family has its roots in three von Langheim brothers, who were the co-founders of Langheim Abbey in 1132. Later the name "de Rotha(ha)" was used. In 1229, reference is made to a Winther and Wolfram "de Rotenhagen" in connexion with an allodial holding of the family rather than a fief. The doorway to the staircase entrance belongs to the late Romanesque-early Gothic period. In 1323 the castle was besieged by the Bishop of Würzburg, Wolfram Wolfskeel von Grumbach, for a year under the pretext of that the family had been involved in counterfeiting and a breach of feudal loyalty. After it was finally captured, the structure was destroyed and, according to a treaty of 1324, was never to be rebuilt. Later, the House of Rotenhan built a new castle, Eyrichshof, further down the hill below the site of Rotenhan.
