Trams are a major form of public transport in Melbourne, the capital city of the state of Victoria, Australia. As of May 2017, the Melbourne tramway network consists of 250 kilometres (160 miles) of double track, 493 trams, 24 routes, and 1,763 tram stops. 

The operator Yarra Trams claims the system is the largest operational urban tram network in the world. Trams are the second most used form of public transport in overall boardings in Melbourne after the commuter railway network, with a total of 206 million passenger trips in 2017–18. 

Trams have operated continuously in Melbourne since 1885 (the horse tram line in Fairfield opened in 1884, but was at best an irregular service). Since then they have become a distinctive part of Melbourne's character and feature in tourism and travel advertising. 

Melbourne's cable tram system opened in 1885, and expanded to one of the largest in the world, with 75 kilometres (46.6 miles) of double track. The first electric tram line opened in 1889, but closed only a few years later in 1896. In 1906 electric tram systems were opened in St Kilda and Essendon, marking the start of continuous operation of Melbourne's electric trams.

Victoria's public transport system was reorganised in 1983 and saw the Melbourne & Metropolitan Tramways Board absorbed into the Metropolitan Transit Authority, which was in turn absorbed by the Public Transport Corporation in 1989.

The network has been operated under contract since the commencement of franchising, following the privatisation of the Public Transport Corporation in 1999. The current private operator contracted to run Melbourne's tram system is Keolis Downer, trading as Yarra Trams.

Ticketing, public information and patronage promotion are undertaken by Victoria's public transport body, Public Transport Victoria. The multi-modal integrated ticketing system, myki, currently operates across the tram network.
