Centro Sociale Leoncavallo is a self-managed social centre in Milan, Italy, which exists since a former factory on via Leoncavallo was squatted in 1975. It was evicted and partially demolished in 1989, then quickly reoccupied and rebuilt. It was evicted again in 1994 and briefly moved to a warehouse for six months before occupying its still extant location on via Antoine Watteau. Activities include concerts, theatre, debates, exhibitions and a radio station. The centre describes itself as Leoncavallo Self-Managed Public Space.

Self-managed social centres in Italy exist in many cities. They are part of different left-wing political networks including anarchist, communist, socialist, and autonomist. The centres tend to be squatted and provide self-organised, self-financing spaces for alternative and noncommercial activities such as concerts, exhibitions, farmers' markets, infoshops, and migrant initiatives. Over time, some but not all projects have opted to legalize their status.
