List of bus routes in Melbourne

Melbourne's bus network is a major transportation system in Australia, comprising around 400 bus routes. The bus network is run by private companies under contract to Public Transport Victoria. Buses in Melbourne use the Myki ticketing system, with the exception of SkyBus services.

Kinetic Melbourne operate approximately 30% of the bus network, signing contracts in 2021 as part of the Melbourne Metropolitan Bus Franchise. The remaining 70% of the network is operated under 23 contracts with other bus operators, all of these contracts were entered into in mid-2018 and will expire in 2025 or 2028.

All bus routes are allocated a number from 150-999, with the exception of SkyBus services. Route numbers below 150 are used by trams. The numbering of a route can tell a bit about the geographical location served, the route's history, or the route's type of operation; for example, routes from the 900 series were historically used by the Victorian Railways, whose buses coordinated with trains on some routes, but now the series is used for the SmartBus and Night Network routes.

SkyBus services run to and from Melbourne and Avalon airports.

Some bus routes have been taken out of operation. They may have been scrapped, replaced (either by another route or a FlexiRide service), incorporated into existing routes, or split. Reasons may include low patronage, confusing routing, or infrequent service patterns.
