Rio Americano High School, colloquially known as Rio, is a public high school in Arden-Arcade, California, just outside Sacramento, serving students in grades 9 through 12 as part of the San Juan Unified School District. Rio Americano students come from the surrounding areas of Arden Park, Arden Oaks, Sierra Oaks, Fair Oaks, Carmichael, Gold River, and to a much lesser extent, the La Sierra community. In recent years, more students have been transferring from other districts and areas, partly due to the shift of Sacramento High School to a charter school. Rio's two rival schools are Jesuit High School and El Camino Fundamental High School because of the schools' close proximity.

Jesuit High School is a private Catholic college-preparatory high school run by the USA West Province of the Society of Jesus in the Sacramento suburb of Carmichael, California. It was founded in 1963 and enrolls about 1,000 young men from throughout greater Sacramento Valley in California.
