The Tongva Sacred Springs are a group of springs located on the campus of University High School in Los Angeles, California. The springs, called Kuruvungna by the native Gabrieleno Tongva people, were used as a source of natural fresh water by the Tongva people since at least the 5th century BC and continue to produce 22,000–25,000 US gallons (83,000–95,000 L) of water a day. The springs are also sometimes referred to as the Gabrieleno-Tongva Springs, the Tongva Holy Springs, and the Sacred Springs. (The deprecated toponym Serra Springs was for Catholic missionary Junípero Serra who supposedly performed mass at the site in 1770.)
