As of the 2020 census, the city had a population of 346,824, making it the most populous city in Orange County, the tenth-most populous city in California, and the 56th-most populous city in the United States. The second largest city in Orange County in terms of land area, Anaheim is known for being the home of the Disneyland Resort, the Anaheim Convention Center, and two professional sports teams: the Los Angeles Angels of Major League Baseball (MLB) and the Anaheim Ducks of the National Hockey League (NHL).

Anaheim was founded by fifty German families in 1857 and incorporated as the second city in Los Angeles County on March 18, 1876; Orange County was split off from Los Angeles County in 1889. Anaheim remained largely an agricultural community until Disneyland opened on July 17, 1955. This led to the construction of several hotels and motels around the area, and residential districts in Anaheim soon followed. The city also developed into an industrial center, producing electronics, aircraft parts and canned fruit. Anaheim is a charter city.
