The Jurupa Mountains, or Jurupa Hills, are a small mountain range of the Peninsular Ranges System, located in the southeastern Pomona Valley, within northwestern Riverside County and southwestern San Bernardino County of the Inland Empire region, southern California.
Mount Jurupa, at 2217feet, is the tallest point in the range. It and the range draw their name from the Rancho Jurupa, an 1838 Mexican land grant, and one of the earliest permanent settlements in the area.
The southern slopes of the range descend into the city of Jurupa Valley and the Pomona Freeway (State Route 60) in Riverside County. The northern slopes descend into the city of Fontana and the community of Declezville in San Bernardino County.
The Pedley Hills are nearby on the eastern side of the Jurupa Mountains, and the Pomona Valley wraps around their northern and western sides.
