city, Polk county, central Florida, U.S., situated amid a large cluster of small lakes, about 15 miles (25 km) east of Lakeland. The area was settled in the 1860s. The city was laid out in 1884 and originally called Harris Corners (for the family who owned a local store) but was later renamed Winter Haven. Fruits and vegetables were grown there, and by the early 1900s citrus groves had been planted, and the city had a canning factory. It was incorporated in 1911 and in 1924 amalgamated with nearby Florence Villa to form the City of Winter Haven.

The citrus industry, phosphate mining, and tourism are the city's economic mainstays. Insurance and manufacturing (including building materials) are also important. The many area lakes provide water sports and fishing opportunities, and the region has a large retiree population. Cypress Gardens, just southeast of the city, is Florida's first theme park (1936). It is noted for its botanical gardens and water ski show, as well as for light shows, a butterfly conservatory, and an aviary. Other attractions include the Water Ski Museum and Hall of Fame and the Florida Citrus Festival, held annually in nearby Auburndale from late January to early February. Polk Community College opened in 1964. Pop. (1990) city, 24,725; Lakeland–Winter Haven MSA, 405,382; (2000) city, 26,487; Lakeland–Winter Haven MSA, 483,924.
