Montserrat (Catalan pronunciation: [munsəˈrat]) is a multi-peaked mountain range near Barcelona, in Catalonia, Spain. It is part of the Catalan Pre-Coastal Range. The main peaks are Sant Jeroni (1,236 m), Montgrós (1,120 m) and Les Agulles (903 m).

It is well known as the site of the Benedictine abbey, Santa Maria de Montserrat, which hosts the Virgin of Montserrat sanctuary. The stone from the mountain is also used for the construction of Sagrada Familia, though recently, the stone began to become more fragile the deeper they quarried, so an alternative source had to be found to complete the construction. In 2018, the stone type needed for the construction was found in a quarry in Brinscall, near Chorley, England.

"Montserrat" literally means "serrated (like the common handsaw) mountain" in Catalan. It describes its peculiar aspect with a multitude of rock formations that are visible from a great distance. The mountain is composed of strikingly pink conglomerate, a form of sedimentary rock. Montserrat was designated as a National Park in 1987. The Monastery of Montserrat which houses the virgin that gives its name to the monastery is also on the mountain, although it is also known as La Moreneta ("the little tan/dark one" in Catalan).
