OC Bus is the transit bus service operated by the Orange County Transportation Authority (OCTA), serving every city in Orange County. Some of the lines serve the Los Angeles County border communities of Lakewood, La Mirada, Cerritos, Artesia, Hawaiian Gardens, and Long Beach. As of November 2025, there are 51 routes in the system.
The agency is the second-largest public transportation provider in the metropolitan area after the Los Angeles County Metropolitan Transportation Authority. Its predecessor agencies include not only the prior Orange County Transit District but also such diverse entities as the Pacific Electric Railway and the South Coast Transit Corporation. In 2005, OCTA was judged America's Best Public Transportation System by the American Public Transportation Association, for its record gains in bus and Metrolink commuter trains ridership that it operates or funds.
The Authority's administrative offices are located in the city of Orange and it maintains bus operations bases in the cities of Garden Grove, and Santa Ana. Keolis operates about 40% of OCTA's Fixed Routes out of the Anaheim and Irvine bases, while Transdev operates OCTA's paratransit base for the authority's ACCESS service, also in Irvine.
All OCTA buses are equipped with bike racks, articulated buses carry two bike racks, while the rest of the fleet carry three bike racks. In addition, all OCTA buses come with free WiFi onboard.
The longest is route 1 (Long Beach–San Clemente) which utilizes Pacific Coast Highway for the vast majority of its route, with trips take an average of 2 to 2.5 hours.

100s (Community Routes) Routes with numbers in the 100s descended from the old RunAbout service that formerly served residential neighborhoods, or provide service to portions of 1-99 routes that have reduced demand. Three routes (129, 143, 153) were truncated from routes 29, 43, 47, 53, and 59 as a result of March 2010 service change; the 153 was later discontinued in February 2023. These routes are operated by Keolis, although between February 2022 and June 2023 OCTA temporarily operated many of these routes in-house except for the 129, 143, and 177, likely due to contractor driver shortages.
