Belle Glade is a city in south-central Florida in the far western part of Palm Beach County, Florida, United States, on the southeastern shore of Lake Okeechobee. It is part of the Miami metropolitan area of South Florida. According to the 2020 U.S. census, the city had a population of 16,698, down from 17,467 in the 2010 census.

Belle Glade (and the surrounding area) is sometimes referred to as "Muck City" due to the large quantity of muck, in which sugarcane grows, found in the area. Despite being located in the South Florida region of the state, Belle Glade is culturally more associated with the Florida Heartland.

For a time during the early to mid 1980s, the city had the highest rate of AIDS infection per capita (37 cases in a population of roughly 19,000) in the United States. According to the FBI, in 2003, the city had the second highest violent crime rate in the country at 298 per 10,000 residents.^{[citation needed]} In 2010, the Palm Beach County sheriff's office estimated that half of the young men in Belle Glade between the ages of 18 and 25 had felony convictions.

The Belle Glade or Okeechobee culture was an archaeological culture that extended around Lake Okeechobee and included the lower Kissimmee River valley. It existed from as early as 1000 BCE until about 1700 CE. The culture is named for the Belle Glade site, which was excavated in the mid-1930s as part of a Civil Works Administration project. The Belle Glade site included a midden and a burial mound.

The town of Belle Glade was founded during the Florida land boom of the 1920s. During that period, there were a series of efforts made to put in place drainage systems to reclaim dry land from the Everglades, including land around Lake Okeechobee. It was hoped that the reclaimed acreage could be put to better use, including agriculture. In 1921 the Florida legislature established an agricultural research station at Belle Glade to study methods of growing crops on reclaimed Everglades land. At that time, there were already 16 settlements on and around Lake Okeechobee, inhabited by around 2,000 people.

A settlement, originally named Hillsboro, was built at what is now Belle Glade in 1925. In 1926 the Florida East Coast Railway extended its system to Belle Glade, which helped the town's development.

A powerful hurricane struck the area on September 16, 1928. The storm winds caused Lake Okeechobee to overflow its banks, inundating towns around the lake and causing widespread damage in Belle Glade. According to figures compiled by the Florida Department of Health, the storm killed 611 people in Belle Glade alone, and a total of over 1,800 statewide. Contemporary accounts stated that most of the dead were Black migrant farmworkers, a "large percentage" of whom were believed to be from the Bahamas. Belle Glade was rebuilt, and a large dike was erected to protect towns around the lake from storm-driven overflows.

German prisoners of war were confined in camps located at Belle Glade and nearby Clewiston during World War II.
