Porta Lodovica was a city gate of the Spanish walls of Milan, Italy, named after Ludovico Sforza.

Today, the name refers to the district (quartiere) of Milan where the gate used to be, which is part of the Zone 5 administrative division.

The gate was named after Ludovico Sforza because he had the idea of enlarging the former "Porta di Sant'Eufemia" to facilitate access to the Santa Maria presso San Celso sanctuary, which was visited by many pilgrims.

In the late 19th century, when new districts developed in the periphery of Milan, several gates and several tracts of the city walls were demolished to make traffic easier.

The district of Porta Lodovica marks the transition from the historic centre to the "Bastions", i.e., the part of the city that was enclosed by the Spanish walls.
