Otto II, Count of Zutphen

Otto II, Count of Zutphen was a Dutch nobleman from the early 12th century. Otto was the son of Gottschalk, Count of Zutphen and Adelheid of Zutphen.

Otto's maternal grandfather may be Otto of Hammerstein, who may have been the first count of Zutphen. Alternatively Adelheid may be a daughter of Ludolf of Zutphen and Mathilda of Hammerstein (daughter of Otto of Hammerstein).

Otto, known as "the rich", married Judith of Arnstein. They had four children:

• Henry II, Count of Zutphen (died before 1134) married Mathilde of Beichlingen, daughter of Kuno, Count of Beichlingen and Kunigunde of Weimar.
• Dirk (Diederik) of Zutphen ( died before 1134). Bishop of Munster.
• Gerard (died before 1134).
• Ermengarde of Zutphen married 1) Gerard II, Count of Guelders and 2) Conrad II, Count of Luxembourg, son of William I, Count of Luxembourg and Luitgard von Beichlingen. Ermengarde was Countess of Zutphen from 1122 to 1138.
