e-tran was the public transit system for the city of Elk Grove, California and parts of south Sacramento.

In 2003, the City evaluated the current contract with SacRT, which would expire in June 2004, and decided to operate its own public transit system, creating E-tran.

APTA lauded the agency's deployment of the "better bus", fitted with high-back reclining seats, parcel racks, wireless Internet access, and bicycle racks, increasing transit access to its citizens, and maximizing connections to other agencies, including SacRT, Amtrak, Capitol Corridor, and Greyhound, providing a "truly viable alternative to the automobile".

Main transfer points are at the Cosumnes River College, Meadowview Light Rail Station and Laguna Town Hall.

In September 2008, the original 21 hybrid-electric buses that were used when the transit system opened on January 2, 2005 were pulled from service.
