Geographic and cultural region in Florida. the metropolitan area made up by the population centers of Miami Dade, Broward, and Palm Beach Counties

South Florida, sometimes colloquially shortened to SoFlo, is the southernmost region of the U. S. state of Florida. It is one of Florida's three most commonly referred to directional regions; the two others are Central Florida and North Florida. South Florida is the southernmost part of the continental United States and the only region of the continental U. S. that includes some areas with a tropical climate. South Florida is dominated by the Miami metropolitan area and the Everglades. It also contains the Florida Keys; three U. S. national parks: Biscayne, Dry Tortugas, and Everglades; and multiple cities.

As with all vernacular regions, South Florida has no official boundaries or status and is defined differently by different sources. A 2007 study of Florida's regions by Ary Lamme and Raymond K. Oldakowski found that Floridians surveyed identified "South Florida" as comprising the southernmost sections of peninsular Florida, meaning from Jupiter, Florida south. That area includes the Miami metropolitan area, defined as Miami Dade, Broward, and Palm Beach counties, the Florida Keys, and the interior region known as the Glades. The term South Florida most commonly refers to the Miami metro’s tri county area, interpretations vary on the inclusion of some other parts of Florida within the South Florida region, such as the inclusion of Southwest Florida and the Treasure Coast. Southwest Florida, representing the state's Gulf Coast, has emerged as a directional vernacular region. Respondents from as far northwest as the Tampa Bay area identified their region as being in Central Florida. Confusing the matter further, the University of South Florida, named in part because of its status as the state's southernmost public university at the time of its 1957 founding, is located in Tampa Florida State Road 70 bisects approximately in the Central Florida region from west to east. However, Tampa is not considered South Florida region. Enterprise Florida, the state's economic development agency, identifies "Southeast Florida" as one of eight economic regions used by the agency and other state and outside entities, including the Florida Department of Transportation. Some entities alternately designate this region "South Florida". Its definition includes much of the same territory as Lamme and Oldakowski's report, except the Gulf Coast and much of the interior Glades region It includes Monroe County and the three metropolitan counties of Miami Dade, Broward, and Palm Beach, as well as the three "Treasure Coast" counties of Indian River, St. Lucie, and Martin to the north.

South Florida is politically diverse, with multiple congressional districts in the region supporting both the Democratic and Republican parties. As evidenced by the 2020 United States presidential election, supporters of the Democratic Party are mostly concentrated in urban areas, as well as areas to the west of and including downtown Key West, rural communities surrounding Immokalee, and the areas surrounding Belle Glade, while supporters of the Republican Party reside in the most costal regions of the Miami area north of Pompano Beach, most of the Everglades, most of the regions between Port St. Lucie and Riviera Beach, Southwest Florida, and a supermajority of the region's inland and rural areas.

The Miami accent is a regional accent of the American English dialect spoken in South Florida, particularly in Miami Dade, Broward, Palm Beach, and Monroe counties. The accent was born in central Miami, but has expanded to the rest of South Florida in the decades since the 1960s. The Miami accent is most prevalent in American born South Floridian youth. The Miami accent is based on a fairly standard American accent but with some changes very similar to dialects in the Mid Atlantic (especially the New York area dialect, Northern New Jersey English, and New York Latino English.) Unlike Virginia Piedmont, Coastal Southern American, and Northeast American dialects, the "Miami accent" is rhotic; it also incorporates a rhythm and pronunciation heavily influenced by Spanish (wherein rhythm is syllable timed).

Lamme and Oldakowski identify several demographic, political, and cultural elements that characterize South Florida and distinguish it from other areas of the state. Many of its differences appear to be driven by its proportionately higher level of migration from the northern U. S. states and from the Caribbean and Latin America, particularly in the densely populated Miami area. Politically, South Florida is more liberal than the rest of the state. While less than 10% of people in either North or Central Florida felt their area was liberal, over a third of South Floridians described their region as such. 38% characterized the area as conservative; 26% as moderate. The economy in South Florida is very similar to that in Central Florida. Compared to the more diversified economy in North Florida, tourism is by far the most significant industry in South and Central Florida, with a much smaller but vibrant agricultural industry.

Lamme and Oldakowski's survey also found some cultural indicators distinguishing South Florida. South Florida is the only region of the state where ethnic foods are as popular as general American cuisine. Floribbean cuisine is a fusion cuisine which developed in South Florida, drawing influence from Floridian, Caribbean, Asian and Latin American cuisines. Additionally, while there was little geographical variation for most styles of music, there was regional variation for both country and Latin music. Country was significantly less popular in South Florida than in North or Central Florida, while Latin was more popular than in the other regions.

There have been several proposals for partitioning the state of Florida to form a separate state of South Florida. Such proposals have usually been made as political statement rather than serious attempts at secession. Reasons often stated are cultural, ethnic, economic, and financial frustrations with the state government in Tallahassee, which is in North Florida. In 2008, the North Lauderdale City Commission passed a resolution calling for a new state of South Florida to be formed from Palm Beach, Broward, Miami Dade and Monroe Counties.
