Kern Transit, formerly Kern Regional Transit, is the operator of mass transportation in Kern County, California. Primarily, it provides inter-regional transportation, connecting outlying regions with the city of Bakersfield (and with each other with a transfer in Bakersfield). It also provides inter-city transportation within specific regions. Kern (Regional) Transit is operated by the Kern County Department of Roads. The agency was founded in 1981. Its headquarters are located in Bakersfield.

In January 2017, operation of Kern Transit was taken over by National Express Transit.

Bakersfield is the central hub for the inter-regional routes. Buses stop at the Downtown Transit Center (operated by Golden Empire Transit), or the Bakersfield Amtrak Station which is also located downtown, or both. Bus bays are used at the Amtrak Station, while none are available at the Transit Center. Buses instead park on Chester Avenue, in front of it. Depending on the route, Kern Regional Transit makes additional stops in Bakersfield, but are generally used either to board or discharge passengers (depending on the direction the bus is traveling).

Additional hubs are located in Frazier Park, Lake Isabella, and Mojave. Passengers transfer from inter-regional routes to inter-city routes that serve the specific region. Many of these routes were requested and funded by local governments, instead of operating their own transit system.

Some local governments have funded their own public transportation system, instead of relying on Kern Regional Transit. These include Arvin (Arvin Transit), Delano (Delano Area Rapid Transit), and Taft (Taft Area Transit). In addition, Shafter and Wasco provide their own Dial-a-ride service, which serves their communities.
