About the town » Los Alamitos, Orange County, California, United States

Los Alamitos ("The Little Cottonwoods" in Spanish) is a small city in Orange County, California. The city was incorporated in March 1960. The population was 11,449 at the 2010 census, down from 11,536 at the 2000 census. It is often mistakenly thought to include the adjacent but unincorporated community of Rossmoor (population just under 11,000) which uses Los Alamitos as its mailing address. Although Rossmoor is not part of Los Alamitos, it is speculated that it may be annexed to the city, or Rossmoor, Seal Beach, and Los Alamitos will combine to form one city. The USA Water Polo National Aquatic Center is located on the US Military Los Alamitos Joint Forces Training Base. The training base includes the Los Alamitos Army Airfield.
