Monistrol de Montserrat (Catalan pronunciation: [munisˈtɾɔl də munsəˈrat]) is a municipality in Bages county in Catalonia, Spain.

The municipality includes the southern two-thirds of the massif of Montserrat and the famous Benedictine monastery of the same name.

The town, known as Montserrat-Vila, is situated on the eastern flank of the massif above the valley of the Llobregat river: it is connected with the monastery (higher up) and with the railway station in the valley (FGC line R5) by the Montserrat Rack Railway (Cremallera de Montserrat).

The bridge over the Llobregat river dates from the fourteenth century.

The municipality includes a small exclave to the north-west.
