The San Bernardino Line is a Metrolink line running between Downtown Los Angeles east through the San Gabriel Valley and the Inland Empire to San Bernardino, with limited service to Redlands. It is one of the three initial lines on the original Metrolink system, along with the Santa Clarita Line (now the Antelope Valley Line) and the Ventura County Line.

As of January 2025, the line has 44 weekday trips (22 in each direction) with most trips operating between Los Angeles Union Station in the west and the San Bernardino Transit Center to the east, however 5 trips are short turns that only operate as far east as the Montclair Transcenter and 1 trip is extended past San Bernardino to serve Redlands–Downtown station. It was the first Metrolink line to run on both Saturday and Sunday, with 16 weekend trips (8 in each direction) operating between Los Angeles and San Bernardino.
