State Road 5 (SR 5) is a mostly-unsigned state highway in the state of Florida. It is mainly signed as US 1 from its south end in Key West, Florida to Jacksonville, Florida, and US 17 from Jacksonville to the Georgia state line at the Saint Marys River. US 1 is SR 15 northwest from Jacksonville.
However, from northern Lantana through Lake Worth to Belvedere Road in West Palm Beach, SR 5 is separate from US 1, which runs to the west on the older but wider Dixie Highway. Here, SR 5 runs along a road named Olive Avenue.
