Disney California Adventure Park is a theme park at the Disneyland Resort in Anaheim, California. It is owned and operated by The Walt Disney Company through its Experiences division. The 72-acre (29 ha) park is themed after Disney's interpretation of California, by the use of Disney, Pixar and Marvel properties. The park opened on February 8, 2001, and is the second of two theme parks built at the Disneyland Resort complex, after Disneyland Park.

An amusement park is a park that features various attractions, such as rides and games, as well as other events for entertainment purposes. A theme park is a type of amusement park that bases its structures and attractions around a central theme, often featuring multiple areas with different themes. Unlike temporary and mobile funfairs and carnivals, amusement parks are stationary and built for long-lasting operation. They are more elaborate than city parks and playgrounds, usually providing attractions that cater to a variety of age groups. While amusement parks often contain themed areas, theme parks place a heavier focus with more intricately-designed themes that revolve around a particular subject or group of subjects.
