Lost Rocks is a climbing area in Joshua Tree National Park in California, managed by the National Park Service.

The area is close to Ryan Ranch Trailhead, about 0.4 miles away, and to the California Riding and Hiking Trail, about 1.1 miles away. The climbing here is trad, with one mixed route, and the grades range from 5.4 to 5.11c. The hardest route is Filet 'o Finger, a mixed climb at 5.11c, while The Downclimb is the easiest at 5.4. The other routes, Fender Bender, SSDDC and Tribal Line, are all 5.7. Spring and fall are the most comfortable times to visit. Typical averages from a nearby weather station in Yucca Valley show April highs around 73°F and October highs around 80°F, while July and August average about 96°F. That station sits roughly 1,100 feet lower than the park, so temperatures at the rocks run cooler. A fee is charged for climbing here.
