Grimbergen Abbey was a Premonstratensian monastery in Grimbergen, Flemish Brabant, Belgium, established in 1128 in the place of an earlier foundation of Augustinian Canons.
The abbey itself was dissolved in 1796 in the aftermath of the French Revolution, but the abbey church of Saint Servatius survived as the parish church of Grimbergen. The building in its present form dates from 1660 and is considered one of the most beautiful and best-integrated Baroque churches in the Low Countries. It was elevated to the status of basilica minor in 1999.
