Soboba Hot Springs are a historic hot springs and resort in Riverside County, California, United States. The springs issued from the side of a steep ravine "with narrow, precipitous sides, and the rock exposed is largely a crushed gneiss...the thermal character of the springs is due to crushing and slipping of the rocks".[4] The Soboba Hot Springs resort was adjacent to the reservation of the Soboba Band of Luiseño Indians.[5] Soboba means hot water in the Luiseño language.[6]

Located along the San Jacinto Fault a little more than a mile from the city of San Jacinto and about five miles southeast of the Gilman Hot Springs, a resort based around the springs was first attempted in 1885. The resort closed in 1969, and the remaining buildings burned in a 1979 arson-ignited wildfire. Soboba Resort Casino, a Native American gaming hotel opened in 2019,[7] is located close to where the springs resort once stood.
