Saddleback Valley refers to the flat and foothill areas west-southwest of the Saddleback mountain peak of the Santa Ana Mountains and east-northeast of the hilly Crystal Cove State Park in South Orange County, California. The region primarily encompasses the cities of Mission Viejo, Lake Forest, and Rancho Santa Margarita, as well as the communities of Coto de Caza and Ladera Ranch. The cities of Aliso Viejo, Laguna Woods, Laguna Hills, and Laguna Niguel, as well as some of Orange County's eastern canyon communities, partially reside within the valley. The southeastern portion of Irvine also encroaches upon the area, but the two are not typically associated with each other.
