Keys of Florida are a coral- and limestone-based archipelago off the southern coast of the State of Florida in the United States. The chain extends southwest from Key Largo near the southern edge of the Florida Bay and the Everglades toward the Dry Tortugas and the Straits of Florida, forming a distinct cultural and ecological region linked to Miami and Tampa Bay. The islands have shaped maritime navigation, Florida Keys National Marine Sanctuary, and historical events involving Spanish Empire, United Kingdom, United States Virgin Islands movements, and Cuban proximity.
The archipelago lies along the rim of the Florida Platform and the Florida Straits, sitting atop Pleistocene and Holocene carbonate formations associated with past sea-level changes related to the Last Glacial Maximum and the Pleistocene epoch. Geomorphic features include exposed Key Largo Limestone caprock, mangrove-fringed shorelines adjacent to Florida Bay, patch reefs linked to Florida Reef Tract, and sand shoals near the Florida Current and Loop Current. The geological development involved influences from the Gulf Stream, Atlantic hurricane activity such as Hurricane Irma and Hurricane Wilma, and sediment transport shaped during events like the Great Miami Hurricane of 1926.
Major islands include Key Largo, Islamorada, Marathon, Big Pine Key, Key West, and the remote Dry Tortugas. Subgroups and local communities reference Upper Keys and Lower Keys, with barrier features near Biscayne Bay, Card Sound, and the Seven Mile Bridge corridor connecting Knight's Key and Pigeon Key. Noted is No Name Key, Sugarloaf Key, Duck Key, Long Key, Spanish Harbor Key, and Cudjoe Key. Offshore reefs and islets include Alligator Reef, Fowey Rocks, and Sombrero Key.
Human presence traces to Tequesta and Calusa peoples before European contact by Juan Ponce de León and Pedro Menéndez de Avilés, followed by contested claims involving the Spanish Empire and British Empire. The islands factored into War of 1812-era maritime operations, the Second Seminole War, and Mexican-American War maritime logistics. Settlements expanded with 19th-century wrecking fleets, aided by figures connected to Henry Flagler railroad initiatives and the Overseas Railroad project engineered under Florida development interests linked to Thomas Edison and Marjorie Kinnan Rawlings era attention. The Keys hosted Cuban refugees after events like the Ten Years' War and later 20th-century migrations tied to Cuban Revolution trajectories and Operation Pedro Pan.
Economic history centers on wrecking, sponging, fishing, and tourism associated with attractions such as Mallory Square, Ernest Hemingway Home and Museum, Southernmost Point Buoy, and recreational diving on the Florida Reef Tract. Contemporary industry includes charter fishing fleets associated with species managed under NOAA Fisheries regimes, hospitality tied to Key West International Airport activity, and marine research by institutions like the Mote Marine Laboratory and Florida Keys Community College. Cultural festivals link to Fantasy Fest, and cruise ship calls from lines such as Carnival Corporation and Royal Caribbean International influence local commerce. The economy responds to federal and state programs from agencies like the National Park Service and Florida Fish and Wildlife Conservation Commission.
The islands encompass habitats including tropical hardwood hammocks, buttonwood mangrove stands, seagrass beds such as Thalassia testudinum meadows, and coral communities within the Florida Keys National Marine Sanctuary. Conservation efforts involve collaborations among National Oceanic and Atmospheric Administration, The Nature Conservancy, Florida Department of Environmental Protection, and NGOs reacting to threats from coral bleaching events noted in association with elevated temperatures and incidents related to Stony Coral Tissue Loss Disease. Protected areas include Dry Tortugas National Park, Key West National Wildlife Refuge, and state-managed zones influenced by international agreements like the Convention on International Trade in Endangered Species of Wild Fauna and Flora when addressing species such as the Key deer and listed species protected under the Endangered Species Act. Restoration projects reference work by Southeast Aquatic Resources Partnership and programs tied to NOAA Restoration Center.
The archipelago's principal transport spine is the Overseas Highway (U.S. Route 1) featuring engineering landmarks such as the Seven Mile Bridge and remnants of the Florida East Coast Railway Overseas Railroad. Aviation access includes Key West International Airport and Marathon Airport, while marine infrastructure comprises seaports at Key West Harbor and marinas supporting ferries to Dry Tortugas National Park and private vessels. Utility and resilience projects have been influenced by federal agencies including Federal Emergency Management Agency and state initiatives responding to storm surge risks documented after Hurricane Wilma and Hurricane Katrina impacts to shipping lanes maintained near the Port of Miami.
Populations blend descendants of Spanish settlers, Bahamians (often called "Conchs"), Cuban immigrants, and migrants from mainland locales like Miami and Tampa Bay, producing a cultural mix visible in sites tied to Ernest Hemingway, Elizabeth Bishop, and performers who have performed at venues like Sloppy Joe's Bar. Demographic patterns reflect seasonal residents and retirees, influenced by policies enacted in Monroe County and regional planning entities such as the South Florida Water Management District. Cultural life includes music and literary references tied to Jimmy Buffett, festivals parallel to Key West Literary Seminar, and culinary traditions featuring locally landed species regulated under Magnuson-Stevens Fishery Conservation and Management Act frameworks.
