Ring Abbey (Ringkloster) was a Benedictine nunnery in Skanderborg Municipality, Denmark.
The Abbey functioned mainly as a school for girls and a retirement home for elder women from the nobility.
Initially small, it became a substantial landowner through donations by the families of the noblewomen accepted as nuns in the Abbey.
During the Danish Reformation, Ring Abbey was confiscated by the crown and given to Lord High Treasurer Mogens Gøye and then to his son-in-law Admiral Herluf Trolle, who were forced to promise to support the remaining nuns, who were allowed to live in the building for life.
In 1571, Ring Abbey were incorporated into Skanderborg parish, and in 1579 lost its market place.
