E-tran was the public transit system for the city of Elk Grove, California and parts of south Sacramento. Public transit in these areas was operated by Sacramento Regional Transit District (SacRT) until 2005, when E-tran began operation under the City of Elk Grove, with bus operations contracted to MV Transportation; subsequently, SacRT took up the contract to operate E-tran in 2019 and then re-annexed E-tran in 2021.
