Olesa de Montserrat (in Catalan; Valencian pronounced as /uˈlɛzə ðə munsəˈrat/) is a municipality in the comarca of Baix Llobregat, in Catalonia, Spain.
Olesa de Montserrat is well known around the nearby places because of its olive oil and textile production, but especially because of its Passion play (La Passió d'Olesa), first documented in 1538. It achieved a world record in 1996, with 726 people acting onstage at the same time.
