The Piccolo Teatro di Milano is a theatre in Milan, Italy. Founded in 1947, it is Italy's first permanent theatre, and a national "teatro stabile", or permanent repertory company, and is considered a theatre of major national and European importance. The theatre has three venues: Teatro Grassi, in Via Rovello, between Sforza Castle and the Piazza del Duomo; Teatro Studio, which was originally intended to be the theater's rehearsal hall; and Teatro Strehler, which opened in 1998 with a seating capacity of 974. Its annual programme consists of approximately thirty performances. In addition, the venue hosts cultural events, from festivals and films, to concerts, conferences, and conventions, as well as supporting the Paolo Grassi Drama School.

Giorgio Strehler was an Italian stage director, theatre practitioner, actor and politician.
