The Abbey of Onze-Lieve-Vrouw ter Nieuwe Plant ("Our Lady of the New Plantation"; Latin: Nova Plantatio Beatae Mariae Virginis), formerly also Roesbrugge Abbey (Dutch: Abdij van Roesbrugge) is a community of Augustinian canonesses belonging to the Congregation of Windesheim.
Located in Roesbrugge from 1239 to the late 16th century, the community then moved into Ypres, West Flanders, Belgium, where it exists today.
The Council of Trent recommended that monasteries should re-settle in or near towns, and the community from Roesbrugge decided to settle permanently in Ypres.
In 1744 the abbey was destroyed by the troops of Louis XV, King of France, during the War of the Austrian Succession.
The sisters were dispersed, but after the Concordat of 1801 between Napoleon and Pope Pius VII were able to buy back a piece of ground immediately adjacent to the site of the former abbey, and began their work again, including the management of a boarding school.
