The Metropolitan Atlanta Rapid Transit Authority (MARTA) operates a number of bus routes in the Atlanta metro region. The main system operates in Fulton, DeKalb, and Clayton counties, although some routes travel into other suburban counties. In 2025, the system had a ridership of 34,316,700, or about 102,700 per weekday as of the second quarter of 2026.

MARTA developed a "wish list" in 2017 to expand service, including buses. However, there was also a plan in 2017 to reduce some bus services, which outraged residents whose buses would have been eliminated. By 2023, their plans for expanded light rail were modified to include bus rapid transit.

In 2025, MARTA announced a complete revamp of their bus system, called "NextGen Bus Network", reducing the number of bus routes from about 113 to 81. The revamp was launched on April 18, 2026.
