The Mojave Freeway, previously known as the Barstow Freeway, is the name given to the segment of Interstate 15 in California between the Cajon Pass and the Nevada state line. It is the principal route between Los Angeles and Las Vegas.

The Ontario (I-15) and Escondido (I-215) freeways meet in Devore , a foothill town just northwest of San Bernardino, merging into the Mojave Freeway. Crossing the San Bernardino Mountains at the Cajon Pass, the freeway enters the Victor Valley and continues northeast through the Mojave Desert. It terminates at the Nevada state line; I-15 continues thereafter to Las Vegas, Salt Lake City, and the cities of western Montana before ending at the U.S.-Canada border.

The Mojave Freeway is fairly busy on weekdays, as it connects the rapidly growing exurbs of the Victor Valley with the Los Angeles area. On weekends and holidays, however, it can be completely jammed with Southern Californians driving to Las Vegas for short vacations.
