Maidstone tram depot is a future depot on the Yarra Trams network in Melbourne. As of March 2024 it is under construction on Hampstead Road, Maidstone near the intersection with Williamson Road, on part of the site of the former Student Village (before that the Maribyrnong Migrant Hostel). The Maidstone depot will be home for the new G-class trams.

The project will involve building a spur pair of tracks on Williamson Road from tram route 82 which will then turn left onto Hampstead Road before they turn right into the new depot.

In 2021, the Department of Transport announced that a new depot would be built on part of the former Victoria University site on Hampstead Road, Maidstone as the home depot for the new G-class trams.

Construction of the new depot began in 2023 and will be operational in 2026.

Trams from the following routes will be stabled and maintained at the Maidstone depot:

• 57: West Maribyrnong to City (Elizabeth Street)
• 59: Airport West to City (Elizabeth Street)
• 82: Moonee Ponds Junction to Footscray
