The Inland Empire is a metropolitan area and region in Southern California, inland of and adjacent to Los Angeles.
It includes the cities of western Riverside County and southwestern San Bernardino County, and is sometimes considered to include the desert communities of the Coachella and Victor Valleys, respectively on the other sides of the San Gorgonio Pass and San Bernardino Mountains from the Santa Ana River watershed that forms the bulk of the Inland Empire; a much broader definition includes all of Riverside and San Bernardino counties.
