The G-class Melbourne tram is a three-section articulated tram, to be introduced onto the Melbourne tram network in 2025. The trams will be low-floor, replacing the Z-class and A-class trams, which will help improve passenger accessibility across the network. The design is based on the Flexity 2 but with pivoting outer bogies.

The trams will be designed, built and maintained by Alstom at its Dandenong factory. Manufacturing of the fleet is scheduled to begin in late 2023. The project also includes a new maintenance and stabling facility in Maidstone, where the trams will be stored following construction.

The initial contract is for 100 new trams, which is the largest domestic order in Australian history,^[1] and includes the requirement for Alstom to maintain the vehicles for 15 years. The trams will be designed to carry 150 passengers and will be 25 metres long.

The fleet will first roll out in the proximity of the Maidstone facility on routes 57, 59 and 82.^[2] As of 2023^[update], these routes operate out of Essendon tram depot.
