Metro Transit, formerly Madison Metro, operates bus services throughout the City of Madison, Wisconsin, United States and several of its suburbs, including Middleton, Fitchburg, Maple Bluff, Shorewood Hills, Sun Prairie, and Verona.

Previously, all routes had passed through Capitol Square, making downtown the only interchange point for cross-town travel.

The 1998 changes redesigned the entire network around four newly created "transfer points" on the north, east, south, and west sides of the city.

The remaining middle schools switched to yellow buses as part of recent route changes.

Various city and regional governments had studied bus rapid transit and other high-capacity systems, including light rail, to serve the Madison area as early as the 1980s, but did not begin formal planning of a bus rapid transit system until 2011.

[17] The transit network focuses on point-to-point service with some routes having different destinations but sharing the same core segments.

[citation needed] The vast majority of service updates reflected in this section went into effect in June 2023.

[18] The University of Wisconsin circulator network was largely unaffected by the changes and retain its previous numbers/ routes.

[22] It cost $195 million to construct, with a majority of funds from a federal grant, and includes articulated buses, center-running bus lanes and stations.

Route W previously interlined with the mainline east-west Route A at the Park & Ride, allowing for a single seat ride from Sun Prairie to downtown Madison, campus and points west, this ended with the launch of the Rapid A BRT service.

Operating costs are paid by Associated Students of Madison, UW Transportation Services, and University Housing.
