Casa Milan, Football club headquarters in Portello district, Milan, Italy

Casa Milan is the AC Milan headquarters in the Portello district, a building designed by Studio Valle of Udine and owned by Inarcassa. Its interiors were fitted out by Fabio Novembre at a cost of 10 million euros, with work by the Roman firm Bondino Engineering. The building houses the Mondo Milan museum, curated by Marco Amato, which holds the club's trophies and memorabilia.

Casa Milan was designed by the Studio Valle of Udine, not by Fabio Novembre, who created the interior fit-out. The club moved its offices from via Turati on 6 October 2013; the building was officially inaugurated on 2 April 2014. Milan bought the property from Vittoria Assicurazioni in February 2021 for about 42 million euros, then sold it to Inarcassa in December 2021 for 57 million euros.

The building reflects AC Milan's identity through its red and black color scheme visible throughout every space. Visitors experience the club's story and achievements directly by walking through galleries and viewing collections of memorabilia.

Casa Milan sits in the Portello area and is served by Milan's metro at the Portello and Lotto stations. The building faces Piazza Gino Valle, a 25,000 m² square that in 2014 was the largest in Milan. The square also holds Emilio Isgrò's Grande cancellatura per Giovanni Testori, a work measuring 23.40 × 2.47 m.

Inside the building, a restaurant allows guests to dine while surrounded by club memorabilia and watching historic matches on screens. This combination of food and football history creates an unusual experience during a visit.
