Siberia is a ghost town in the Mojave Desert of San Bernardino County, California, United States. It lies along historic Route 66 between Bagdad and Ludlow, in the ZIP code 92357 and area code 760.
Siberia was a water stop and a rail siding for the Santa Fe Railroad and a motorist stop on U.S. Route 66 until it faded out after the 1973 opening of Interstate 40, which bypassed the town. Since 2001, all traces of the town have been removed.
The site was the setting for a 1992 comedy-drama movie, Siberia, about low-income residents struggling to "live simple" in a trailer park in the middle of the Mojave Desert.
