The Metro Tunnel, formerly known as Melbourne Metro Rail (MMR), is an underground rapid transit project currently under construction in Melbourne, Victoria, Australia. It involves the construction of twin 9-kilometre (5.6 mi) rail tunnels between South Kensington (north west of the Melbourne central business district) and South Yarra (in the south east) with five new underground stations. The tunnel will connect the Pakenham and Cranbourne lines with the Sunbury line, creating a new high-frequency cross-city line that bypasses Flinders Street station and the City Loop. The line is also planned to serve Melbourne Airport via a new branch line west of Sunshine.

The project will enable the operational separation of various existing lines on Melbourne's rail network and increase the capacity of the system to metro-style frequencies. The Metro Tunnel has high-capacity signalling and platform screen doors, both a first for Melbourne.

The state government began planning the project in 2015. Initial construction works commenced in early 2017. Sections of the Melbourne central business district, including City Square and parts of Swanston Street, were closed to enable construction of the tunnel and stations. Tunnelling began in 2019 and was completed in 2021. Originally expected to be completed in 2026, the Metro Tunnel will open in 2025. The project is being delivered by the Victorian Infrastructure Delivery Authority, at an estimated cost of $12.8 billion.
