Quedlinburg (German pronunciation: [ˈkveːdlɪnbʊʁk]) is a town located north of the Harz mountains, in the district of Harz in the west of Saxony-Anhalt, Germany. In 1994 the medieval court and the old town was set on the UNESCO world heritage list.

Until 2007 it was the capital of the district of Quedlinburg. Some places in town with Romanesque architecture are part of the holiday route Romanesque Road, such as St Servatius' church at the castles hill, St Wigbert's church down the valley and St Maries church on the Montsion's hill ('Muenzenberg').

The town of Quedlinburg is known since at least the early 9th century, when a settlement known as Gross Orden existed at the eastern bank of the river Bode. As such the city is first mentioned in 922, as part of a donation by Henry the Fowler. The records of this donation were collected at the abbey of Corvey.

After Henry's death in 936, his widow Saint Mathilda founded a religious community for women ("Frauenstift") on the castle hill, where daughters of the higher nobility were educated. The main task of this collegiate foundation, Quedlinburg Abbey (where the Annals of Quedlinburg were compiled), was to pray for the memory of King Henry and the rulers that came after him. The first abbess was Mathilde, granddaughter of Henry and Saint Mathilde.
