Protected wilderness area in California, United States

Mojave National Preserve is a United States National Preserve located in the Mojave Desert of San Bernardino County, California, US, between Interstate 15 and Interstate 40. The preserve was established October 31, 1994, with the enactment of the California Desert Protection Act by the United States Congress, which also established Joshua Tree National Park and Death Valley National Park as National Parks. Previously, some lands contained within the Preserve were the East Mojave National Scenic Area, under the jurisdiction of the Bureau of Land Management. At , within the contiguous United States it is the third largest unit of the National Park System and the first largest National Preserve. The preserve was created within the Pacific West Region of the National Park Service and remains within that jurisdiction today. Natural features include the Kelso Dunes, the Marl Mountains and the Cima Dome, as well as volcanic formations such as Hole in the Wall and the Cinder Cone Lava Beds. The preserve surrounds Providence Mountains State Recreation Area and Mitchell Caverns Natural Preserve, which are both managed by the California Department of Parks and Recreation. Impressive Joshua tree forests are found in parts of the preserve. The forest covering Cima Dome and the adjacent Shadow Valley is the largest and densest in the world. In August 2020, a wildfire destroyed 1.3 million Joshua Trees around Cima Dome. The ghost town of Kelso is found in the preserve, with the defunct railroad depot serving as the Visitor Center. The preserve is commonly traversed by 4 wheel drive vehicles traveling on the historic Mojave Road. Climate in the preserve varies greatly. Summer temperatures average , with highs exceeding Elevations in the preserve range from 7929 feet (2417 m) at Clark Mountain to 880 feet (268 m) near Baker. Annual precipitation varies from near Baker, to almost in the mountains. At least 25% of precipitation comes from summer thunderstorms. Snow is often found in the mountains during the winter.

The preserve faces challenges based on its lack of funding, as of 2018 the preserve had a deferred maintenance of $118,036,341. This lack of funding has primarily lead to infrastructure disrepair which, in combination with the reckless driving prevalent among visitors, has caused a significant threat to the endangered Desert Tortoise population within the preserve. In addition to the tortoise's threatened population, the Prairie Falcon and the Bighorn Sheep are both at a risk within the preserve. A common solution provided to help save this population is to install wildlife crossings over the main roads within the preserve, though this is currently not possible with the funding provided.
