Wild Rivers was a water park in Irvine, California. It opened in 1986 on the site of the former Lion Country Safari. Following the expiration of its lease with the The Irvine Company, it closed permanently on September 25, 2011. In July 2012, the Orange County Board of Supervisors approved a 25-year, $30 million lease with Wild Rivers on a parcel of county-owned land in Irvine, located in between the Orange County Great Park and Irvine Transportation Center. A new, larger Wild Rivers park is scheduled to open in Temecula, California, in May 2014.

Before Wild Rivers was built, the land was a drive-through zoo called Lion Country Safari, but it went bankrupt and closed in the 1984. Construction on the Wild Rivers "Mountain" began in 1985 and the park itself opened in 1986. The water park utilized a lot of buildings left over from the land's previous occupant. A few years later it opened the first side by side wave pools in the country.

General tickets, for guests over 48" tall, cost $34.98 and junior tickets, for guests under 48", cost $21.98. Admission after 4:00 p.m. was $21.98 ($16.98 for juniors). Children under 2 years old and seniors over 65 years old could enter free.
