U.S. Route 331 (US 331) in Florida is a north–south United States Highway. It runs 49 miles (79 km) from Santa Rosa Beach north to the Alabama State Line in Walton County. The hidden state routes are State Road 83 from Santa Rosa Beach to DeFuniak Springs, State Road 10 in DeFuniak Springs, and State Road 187 from DeFuniak Springs to Alabama. One concurrency exists with US 90 in DeFuniak Springs.

U.S. Route 331 begins at U.S. Route 98 in Santa Rosa Beach. From there it runs north towards a long concrete slab bridge over Choctawhatchee Bay. The bridge ends at Wheeler Point, and the road makes a sharp curve to the northeast where it encounters an intersection with County Road 3280, and then turns straight north again. Running along the eastern edge of Mallery Bayou, and LaGrange Bayou, the road makes a less drastic northeastern curve at the bridge over Ramsey Brook, and it eventually intersects State Road 20 on the eastern edge of Freeport. The road continues on this trajectory thanks to a 2007 FDOT construction project, but eventually straightens before approaching the northern terminus of State Road 883(former US 331/SR 83) in Owl's Head. From that point it runs along the eastern edge of Eglin Air Force Base, which includes the Eglin Wildlife Management Area. This territory ends across the street from the intersection of Edgewood Circle. After the intersection with Indian Creek Ranch Road, US 331/SR 83 makes a slight northwest curve to meet the southern end of County Road 278 (Coy Burgess Loop). The road runs straight north from there and becomes a divided highway as it approaches the north end of CR 278 just south of Interstate 10 at Exit 85 in DeFuniak Springs. Within the city, US 331/SR 83 remains a divided highway running in the same trajectory, where the only intersection of any level of importance is CR 280(Bob Sikes Road). After the intersection with Myrtle Avenue, it takes another slight curve to the northeast. Two more local intersections will be encountered before the road runs beneath a bridge for the CSX P&A Subdivision, and a parallel bridge with Baldwin Avenue just before the intersection with U.S. Route 90, where both U.S. Route 331 and SR 83 split into two separate concurrencies; US 331 turns left while SR 83 turns right. US 90/331 curves northwest where it encounters the western terminus of Baldwin Avenue, the very city street it crosses under on the north side of the P&A Subdivision. After this it runs along the same railroad line where it encounters the DeFuniak Springs Country Club, but at the eastern edge of DeFuniak Springs Airport, the concurrency ends as US 90 heads west towards Pensacola, while US 331 turns north onto the two-lane hidden SR 187.
