Portello is a district ("quartiere") of Milan, Italy, part of the Zone 8 administrative division of the city, located north-west of the centre.

It is best known as a car-manufacturing area, as it used to house facilities of Alfa Romeo (now dismissed),[1] Darracq, Citroën, and Fiat.

Portello was one of the major urban requalification process in Milan, as the former Alfa Romeo area (385,000 m²) is now being restructured.

The project includes a major park[2] called Parco Vittoria[3] and what will become the largest plaza in Milan[4] (20,000 m²),[5] as well as commercial, service and housing infrastructures.

The design of Parco Vittoria, by architects Charles Jencks and Andreas Kipar, includes several unusual elements, and it is based on the general theme of time.
