Johann Christoph von Westerstetten (6 January 1563 - 28 July 1637) was Prince-bishop of Eichstätt, Bavaria, Germany, during the Thirty Years' War.

[1] Johann Christoph von Westerstetten is well known for the large number of witch trails conducted during his authority.

[2][3][4] In Ellwangen he began systematically persecuting witches and continued the witch-hunt in Eichstätt.

[citation needed] In 1630, King Gustavus Adolphus of Sweden landed in Germany and threatened to invade Bavaria.

In 1631, Westerstetten came to the Jesuit College of Ingolstadt, perhaps seeking the protection of Duke Maximilian.
