A transit map is a topological map in the form of a schematic diagram used to illustrate the routes and stations within a public transport system—whether this be bus, tram, rapid transit, commuter rail or ferry routes. Metro maps, subway maps, or tube maps of metropolitan railways are some common examples.

The primary function of a transit map is to facilitating the passengers' orientation and navigation, helping them to efficiently use the public transport system and identify which stations function as interchange between lines.

Transit maps can usually be found in the transit vehicles, at the platforms or in printed timetables. They are also accessible through digital platforms like mobile apps and websites, ensuring widespread availability and convenience for passengers.
