U.S. Route 231 (US 231) in Florida is a north–south United States Highway. It runs 52 miles (84 km) from Panama City north to the Alabama State Line in Bay and Jackson Counties. The entire route is also unsigned State Road 75 (SR 75), and is a four-lane highway throughout the state whether the road is divided or not.

U.S. Route 231 begins in Panama City at US Business Route 98 (Sixth Street) as a continuation of Harrison Avenue, which spans as far south as the Panama City Marina. Harrison Avenue runs straight north and south as far south as Fourth Street and serves as the point in the city where intersecting west-to-east streets change their names from "West #th Street," to "East #th Street." After crossing U.S. Route 98 (15th Street), US 231 intersects an at-grade railroad crossing with the Atlanta and Saint Andrews Bay Railway and moves onto a four-lane momentarily divided highway that runs parallel to that very crossing, while Harrison Avenue becomes State Road 391. For the rest of its journey through the state US 231 runs as a four-lane divided highway, except in specific towns and cities. After US 231 leaves Harrison Avenue, the tracks that run alongside the northbound lane are hidden by small trees. Sparse development exists on the opposite side which increases as the road moves north. One other intersection (East 19th Street) can be spotted between some shopping centers, and the first major intersection since Harrison Avenue which is State Road 77 (North Cove Boulevard), the northeast corner of which is occupied by the Panama City Mall. After this it intersects Edwards Drive, which while only a local road leading to an industrial area across the tracks, also has an intersection with Industrial Drive which is the address of the headquarters of Bay Line Railroad the company that inherited the A&SAB railroad line running along US 231. North of there and some more local intersections it has an at-grade interchange with State Road 368 (East 23rd Street). Continuing at the same trajectory and intersecting another group of local streets, it briefly enters Hiland Park where it intersects SR/CR 389 and just north of this, the eastern terminus of County Road 2312 (East Baldwin Road), the. It is only after this point that the road becomes a divided highway, but remains along the same trajectory, and runs along that same railroad line even as it enters a formerly incorporated town known as Cedar Grove, where it becomes slightly less urban and eventually serves as the eastern terminus of State Road 390, and shortly after this, the southern terminus of County Road 2321 (formerly SR 77A). Still along the same trajectory, it has a short concurrency with County Road 2293 between Titus Road and John Pitts Road, the latter of the two which also contains County Road 2315 (former State Road 719).
