The Milan tramway network (Italian: Rete tranviaria di Milano) is part of the public transport network of Milan, Italy, operated by Azienda Trasporti Milanesi (ATM).

In operation since 1881, the network is currently 157 km (98 mi) long, making it one of the biggest in the world. It has the unusual track gauge of 1,445 mm (4 ft 8+78 in) (Italian gauge), and comprises 17 urban lines.

While the Milan metro is characterized by a low level of centrality, with no more than two lines ever crossing each other at any of the interchange stations, the tram network is substantially centralized, with nearly half of the lines passing or terminating around Piazza del Duomo, the city central square.
