Laguna Woods (Laguna, Spanish for "Lagoon") is a city in Orange County, California, United States. The population was 16,192 at the 2010 census, down from 16,507 at the 2000 census with a median age of 78. About ninety percent of the city consists of Laguna Woods Village, a private gated retirement community, formerly known as Leisure World.
