Lake Havasu City (/ˈhɑːvəsuː/, HAH-və-soo) is a city in Mohave County, Arizona, United States. As of the 2020 census, the population of the city was 57,144, up from 52,527 in 2010. It is served by Lake Havasu City Airport.

The community first started during World War II as Site Six, an Army Air Corps rest camp on the shores of Lake Havasu. In 1958, American businessman Robert P. McCulloch purchased 3,353 acres (13.57 km) of property on the east side of the lake along Pittsburgh Point, a peninsula that would eventually be transformed into an island.

After four years of planning, McCulloch Properties acquired another 13,000 acres (53 km) of federal land in the surrounding area. Lake Havasu City was established on September 30, 1963, by a resolution of the Mohave County Board of Supervisors, as the Lake Havasu Irrigation and Drainage District, making it a legal entity (the act is referenced in resolution #63-12-1).

McCulloch Properties flew in prospective residents from around the United States for free in what became a substantial air operation. To qualify, prospective customers were required to put down a fully refundable deposit. McCulloch Properties acquired over a half-dozen commercial aircraft and in 1970, bought a small charter carrier, converting the operation into its own certificated airline, McCulloch International Airlines. From 1964 through 1978, 2,702 flights were made to Lake Havasu City bringing in prospective buyers.

Lake Havasu City was incorporated in 1978.

London Bridge crosses the narrow Bridgewater Channel that leads from Lake Havasu (a segment of the Colorado River) to Thompson Bay (also on the river). Hoping to attract tourists and prospective buyers of residential lots, McCulloch bought it for US$2.5 million from the City of London, England, when the bridge was replaced in 1968. The bridge was disassembled on contract with Sundt Construction of Tucson, and the marked stones were shipped to Lake Havasu City and reassembled by Sundt for another US$7 million. The construction took three years to complete.

McCulloch gave an acre of land in Lake Havasu City to London. When Lake Havasu City wanted to use this land for a visitors' center, London leased it back for a quit rent of a Hopi Kachina figure.

Since its inauguration on October 5, 1971, London Bridge has become the second-largest tourist attraction in Arizona, after the Grand Canyon.

Lake Havasu City is an active event destination for a wide range of people. During spring months, the community is joined by university students for spring break. In 1995, Lake Havasu City was featured during MTV's Spring Break coverage. Attendance during Spring Break has taken a downturn in recent years, as the city has declined to issue permits to the large party organizers.

For boaters, March to September are the prime months on Lake Havasu. The city is also home to the International World Jet Ski Final Races, multiple professional fishing tournaments, custom boat regattas, the Western Winter Blast pyrotechnics convention, Havasu 95 Speedway, the Chilln-n-Swilln Beer Festival annual charity event, the Havasu Triathlon, and the Havasu Balloon Festival & Fair.

During the winter months, the community is joined by retirees from colder regions of the country and Canada. During this period, multiple events are held on McCulloch Boulevard. Typically during the second weekend of February, McCulloch Boulevard is home to Winterfest, an annual event which draws thousands of visitors and residents for two days of food, activities, entertainment, and products from over 200 vendors from across the United States.

C. V. Wood, who designed Disneyland, was hired by Robert McCulloch to lay out Lake Havasu's unique road system.

In the early stages of development of the city, McCulloch Properties operated a fleet of secondhand airliners such as the Lockheed Constellation and the Lockheed L-188 Electra to fly prospective property purchasers to the area from California and elsewhere in the United States.
