city, Broward county, southeastern Florida, U.S., on the Atlantic Ocean, just south of Boca Raton. The site, once a pineapple- and vegetable-growing area, was first settled about 1890; in 1896 the Florida East Coast Railway came through the community, which was named Deerfield for the deer that roamed along the Hillsboro River. It developed as a shipping centre for fruits and vegetables. The construction of the Hillsboro Canal (1911) and a bridge across the Intracoastal Waterway to the beach (1917) gave impetus to the growth of the town, which was incorporated as Deerfield in 1925. Renamed Deerfield Beach in 1939, it became a residential resort with tourism as its economic mainstay. City status was achieved in 1951. The city's economy remains based on tourism, and it is also a distribution centre and retirement area. Loxahatchee National Wildlife Refuge is about 10 miles (16 km) to the northwest. Pop. (1990) 46,325; (2000) 64,583.
