U.S. Highway 1 (US 1) in Florida runs 545 miles (877 km) along the state's east coast from Key West to its crossing of the St. Marys River into Georgia north of Boulogne and south of Folkston. US 1 was designated through Florida when the U.S. Numbered Highway System was established in 1926. With the exception of Monroe County, the highway runs through the easternmost tier of counties in the state, connecting numerous towns and cities along its route, including nine county seats. The road is maintained by the Florida Department of Transportation (FDOT).

From its national southern terminus in Key West, US 1 carries the Overseas Highway, which is the Keys's main highway, north to the mainland, entering South Florida. From South Florida to Jacksonville, US 1 runs close to the coastline of the Atlantic Ocean and the Intracoastal Waterway, generally east of Interstate 95 (I-95) and west of State Road A1A (SR A1A), running roughly parallel with both roads. North of Jacksonville, US 1 curves inland toward the St. Mary's River as it enters Georgia.

As is the case with all Florida roads with national designations, the entirety of US 1 has a hidden FDOT designation:

SR 5 from Whitehead Street/Fleming Street in Key West to Federal Highway (SR 5 north) in Lantana, Belvedere Road in West Palm Beach to the I-95/Kings Avenue (SR 5 north) interchange in Jacksonville, and the Main Street (SR 5 south) on/offramps south of the Main Street Bridge to US 1 Alternate (US 1 Alt.)/US 17 in Jacksonville.
SR 805 from Federal Highway in Lantana to Belvedere Road in West Palm Beach.
SR 9 from the I-95/Kings Avenue interchange in Jacksonville to the Main Street exit heading toward the Main Street bridge via the I-95 service road.
SR 10 from the Atlantic Boulevard (US 90 east/SR 10 east) interchange to Beaver Street (US 90 west/SR 10 west) in Downtown Jacksonville via Main Street.
SR 115 from US 1 Alt./US 17 in Jacksonville to the junction with I-95/SR 15 south/SR 115 north via the Martin Luther King Jr. Parkway.
SR 15 from the I-95 interchange in Jacksonville to the Georgia state line near Boulogne.

Among other designations, US 1 is a designated Blue Star Memorial Highway along its entire route through the state.^[2] Markers are placed at various locations, including one in Rockledge and Fort Lauderdale.
