San Juan Hot Springs, also San Juan Capistrano Hot Springs, is a geothermal area in what is now Ronald W. Caspers Wilderness Park, near Cleveland National Forest, in Orange County, California in the United States. The springs were used by the Indigenous peoples of the region, and were an integral part of the dominion of Misíon San Juan Capistrano. They were later developed and used, on and off for a hundred years, as a resort area of post-settlement Southern California. The 52 springs were designated Orange County Historic Landmark No. 38 in 1989.
