For the present province also called "Guelders" in English, see Gelderland.

Guelders (Dutch Gelre, German Geldern) is the name of a historical duchy in the Low Countries. The present province of Gelderland (English also Guelders) in the Netherlands occupies most of the area of the former duchy. The duchy was named after the town of Geldern , which is now in Germany.

Guelders was often at war with the county of Holland and the bishopric of Utrecht, until the dukes of Burgundy acquired the whole area. The duchy was divided into four quarters:

• the quarter of Arnhem, also called the Veluwe
• the quarter of Nijmegen, also called the Betuwe
• the quarter of Zutphen
• the quarter of Roermond (now in the province of Limburg), also called the Upper Quarter of Guelders

When the northern Netherlands revolted against Philip II of Spain, the three northern quarters became part of the United Provinces, while the Upper Quarter remained a part of the Spanish and later the Austrian Netherlands.
