The Guttenberg family is a prominent Franconian noble family. It traces its origins back to 1149 with a Gundeloh von Blassenberg (Plassenberg), though the first mention in a document is dated 1158. The name Guttenberg is derived from Guttenberg in present-day Bavaria, and it was adopted by a Heinrich von Blassenberg around 1310.
