Mulberry is a city in Polk County, Florida, United States. The population was 3,817 at the 2010 census. Mulberry is home to Badcock Home Furniture. It is part of the Lakeland– Winter Haven Metropolitan Statistical Area, with parts of unincorporated Lakeland on its northern boundary. Mulberry is home to the 334 acre Alafia River Reserve.
The first white settlers appeared in the Mulberry area in the 1840s.  The first industry in the area was logging the longleaf yellow pine which dominated the area. Eventually the settlement grew to include log homes, stores, and saloons. The nearest sheriff and jail was hours away in Bartow and the town resembled a scene from the Old West as mob rule prevailed. Everyone carried a gun and Monday morning was a busy time for the coroner as he dealt with the victims of Saturday night's "troublemakers." 
The town had no official name, but the railroad which came through town stopped at a mulberry tree to let off passengers and drop off the mail.  The old mulberry tree became the de facto meeting place in town, and eventually gave the town its name. Several hangings took place from the mulberry tree.  In 1886, phosphate rock was discovered in the Peace River, and the dominant industry went from forestry to mining. The phosphate industry gave the town stability and Mulberry was incorporated in 1901. In 1910 Mulberry's Masonic lodge was established and still is around today.
By 1919, many miners had joined the International Union of Mine, Mill, and Smelter Workers. In April, the union called a strike asking for a minimum wage and an eight-hour work day. The mining companies brought in scabs from Georgia, and put down the strike by shooting up the town, killing two citizens. 
Several black people were lynched in the early 1900s. 
- Robert Davis June 27, 1900
- Dan Kennedy May 3, 1903
- Henry Gordon May 20, 1903
- John Bapes August 21, 1906
On August 19, 1919, Prairie Pebble Mine guards shot and killed two black citizens, including a two-year-old boy. 
According to the United States Census Bureau, the city has a total area of 3.2 square miles (8.3 km²), of which 3.1 square miles (8.0 km²) is land and 0.1 square mile (0.4 km²) (4.36%) is water.

On June 15, 1994, a sinkhole appeared in a toxic waste disposal pond near the city of Mulberry. Phosphogypsum, the byproduct of the phosphate fertilizer industry, is highly toxic and mildly radioactive. The 110 feet diameter and 200 feet deep sinkhole dumped this toxin into caves that lead to the Floridan Aquifer. Drinking water for over ten million Florida residents comes from this aquifer.  The company mining the phosphate, IMC-Agrico, now a part of The Mosaic Company, started the sinkhole remediation process immediately. It has spent over $6 million trying to repair the damage to the Florida water supply.  
On August 27, 2016, the Mosaic Company discovered a giant sinkhole under a gypsum stack. Over 200 million gallons of water contaminated with phosphogypsum disappeared into its 45-foot wide maw.
