Gutenburg Castle (German: Burg Gutenburg, also Gutenberg, Guttenberg, Weitersheim, or Weithersheim), is the ruin of a hill castle above the village of Gutenberg in the county of Bad Kreuznach in the German state of Rhineland-Palatinate.

Following the extinction of the House of Sponheim (the Kreuzenach line died out in 1414 and the Starkenburg line in 1437) the castle went to the Lower Sponheim lords (mainly the Margraviate of Baden and Electoral Palatinate).

The castle lost its importance over time, was destroyed during the Thirty Years' War and fell into ruins.

In the copperplate by Daniel Meisner in the Thesaurus philopoliticus (published 1623f.)

The castle consisted of an inner ward completely surrounded by a ring-shaped outer ward, protected by curtain walls with mural towers as well as a neck ditch.
