Disneyland Park is a theme park located in Anaheim, California, owned and operated by the Walt Disney Parks and Resorts division of The Walt Disney Company. Known as Disneyland when it opened on July 18, 1955, and still colloquially known by that name, it is the only theme park to be designed and built under the direct supervision of Walt Disney. In 1998, the theme park was re-branded "Disneyland Park" to distinguish it from the larger Disneyland Resort complex.
