Günther the Violent (German: Günther der Gewalttätige) was a German wizard who played Stichstock. The painting Günther der Gewalttätige ist der Gewinner (Gunther the Violent is the Winner), painted in 1105, depicts him.
The name Günther is from the Germanic name Gundahar, derived from the elements gund "war" and hari "army, warrior". This was the name of a semi-legendary 5th-century Burgundian king. He appears in the Germanic saga the Nibelungenlied which has him married to the Icelandic queen Brünhild.
