Grimbergen Abbey is 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. After the French Revolution the abbey was reinstated. The building in its present form dates from 1660. It was elevated to the status of basilica minor in 1999.
