Porta Ticinese is a former city gate of Milan, Italy. The gate, facing south-west, was first created with the Spanish walls of the city, in the 16th century, but the original structure was later demolished and replaced in the early 19th century. The name "Porta Ticinese" is used both to refer to the gate proper and to the surrounding district, part of the Zone 6 administrative division. In the same district there is also a medieval gate with the same name, although in common speech the name "Porta Ticinese" is usually assumed to refer to the 19th century gate.

The city Milan, Italy, has had three different systems of defending walls. The oldest, Roman walls were developed in two stages, the first in the Republican and the second in the Imperial era. The second wall system was realized in the Middle Ages, after the destruction of the city by Frederick I Barbarossa. Finally, the latest wall system was built by the Spanish rulers. While very little remains of these walls, their structure is clearly reflected in the urbanistic layout of the city. In particular, modern Milan has two roughly circular rings of streets, namely the "Cerchia dei Navigli" and the "Cerchia dei Bastioni", which essentially correspond to the Medieval and Spanish walls, respectively. Note that a third ring of roads just beyond the Inner Ring Road, called the External Ring Road, does not owe itself to any old city walls; but was part of the 1884 Beruto Plan for the city of Milan, created and named after a municipal engineer and public servant to the local city government.
