Franz Arnold von Wolff-Metternich zur Gracht (* 9. Mai 1658 auf Schloss Gracht in Liblar, heute zu Erftstadt; † 25. Dezember 1718 in Schloss Ahaus) war Fürstbischof von Paderborn und Münster.
The Bishopric of Münster was an ecclesiastical principality in the Holy Roman Empire, located in the northern part of today's North Rhine-Westphalia and western Lower Saxony. From the sixteenth to the eighteenth centuries, it was often held in personal union with one or more of the nearby ecclesiastical principalities of Cologne, Paderborn, Osnabrück, Hildesheim, and Liège.

Münster was bordered by the United Provinces to the west, by Cleves, Vest Recklingh, ausen, and Mark in the south, Paderborn and Osnabrück in the east. In the north and north-east it bordered East Frisia, Oldenburg and the Electorate of Hanover (est. 1692).

As with all the other prince-bishoprics of the Holy Roman Empire, it is important to distinguish between the Prince-Bishopric of Münster and the Diocese of Münster although both entities were ruled by the same individual. The dioceses were generally larger than the corresponding prince-bishoprics and in the parts that extended beyond the prince-bishopric, the prince-bishop's authority was strictly that of an ordinary bishop and limited to spiritual matters.
