Nikolaus von Ybbs

Nikolaus von Ybbs (c. 1275–1340) was a cleric from Ybbs an der Donau who probably studied law at Bologna and served in the royal chanceries of Albert I and Henry VII before his election as prince-bishop of Regensburg on 19 March 1313.

In the German throne dispute he backed Louis IV of Bavaria against Frederick the Fair, and his see was ravaged and later placed under interdict for supporting the excommunicated emperor.

He redeemed Donaustauf from pledge, and his diocese's first parish register was compiled around 1326 during his episcopate. He died at Oberalteich Abbey on 11 October 1340.
