St. Nicholas' Priory (Danish: Sankt Nikolai Kloster) was a Benedictine nunnery founded in 1170 in Ribe, Denmark.
After allegations of unruliness and impropriety during the 1160s the nuns were moved out in 1170 to a new priory built for them by Bishop Ralph, closer to Ribe and episcopal supervision.
[1] The new priory at Ribe, dedicated to Saint Nicholas, consisted of a quadrilateral enclosure, of which the church formed one side and ranges of conventual buildings the other three.
The prioress ran the community, while a local nobleman held the office of provost (or honorary prior) and represented the nuns in secular matters.
The former priory was reopened as a secular institution where a few of the nuns were allowed to live until 1560, when the citizens of Ribe complained about the cost of maintaining all ten churches and four monasteries and the leper hospital.
