U.S. Route 19 in Florida runs 264 miles (425 km) along Florida's west coast from an interchange with U.S. Route 41 in Memphis, Florida, south of Tampa, and continues to the Georgia border north of Monticello, Florida.

US 19 remains independent of I-75, even as the routes converge in the Tampa Bay Area. The route is co-signed with Interstate 275 over the Sunshine Skyway Bridge, a cable-stayed bridge over the mouth of Tampa Bay, US 98 between Chassahowitzka and Perry, Alternate US 27 between Chiefland and Perry, and US 27 between and Perry and Capps.

The "secret" designation for US 19 in Florida between Memphis and Perry is State Road 55. Between Perry and Capps, it follows State Road 20, and between Capps and the Georgia border, it follows State Road 57.

The road begins at an interchange with U.S. Route 41 in Manatee County, and remains independent until the interchange with Interstate 275 at Exit 5, where it overlaps I-275 across the Sunshine Skyway Bridge, the terminus of which is at Interstate 275 & State Road 682 at Exit 17.
