Destin is a city in Okaloosa County, Florida, United States, serving as a principal component of the Crestview–Fort Walton Beach–Destin metropolitan statistical area. Situated on Florida's Emerald Coast, it occupies a peninsula that separates the Gulf of Mexico from Choctawhatchee Bay. This landform was originally a barrier island connected to the mainland by hurricanes and sea-level changes before becoming technically an island again in the 1940s with the completion of the Choctawhatchee-West Bay Canal.

The city is named after Leonard Destin, a New London, Connecticut fishing captain who settled in the area between 1845 and 1850. He built a New England colonial home near what is now the Moreno Point military reservation, where his descendants fished for decades. Condominiums were first constructed during the 1970s, but Destin did not incorporate as a municipality until 1984, after which it experienced rapid growth and development.

Destin styles itself as the World's Luckiest Fishing Village and claims to have Florida's largest fishing vessel fleet. The city features white beaches with sand derived from Appalachian quartz crystal, creating emerald green waters that attract tourists. Key geographical features include East Pass, the only outlet of Choctawhatchee Bay into the Gulf, and Norriego Point, which protects the harbor. The area also includes Henderson Beach State Recreation Area and portions of the Gulf Islands National Seashore.

Tourism is central to the local culture, with over 80% of the Emerald Coast's annual visitors traveling to Destin. Annual events include the Destin Fishing Rodeo, held since 1948, and the Destin Seafood Festival in October. Visitors charter fishing vessels from the harbor and utilize twelve beach access points. The economy relies heavily on real estate, with many high-rise condominiums and vacation rentals located primarily south of US Highway 98 near the Gulf.

The population was 13,931 at the 2020 census, rising from 12,305 in 2010. During tourist season, the population increases to approximately 40,000. Primary access is via US Highway 98, which connects Pensacola and Panama City, or by air through Okaloosa Regional Airport. The city faces environmental challenges, including coastal erosion and inundation risks, having received funds from the Deepwater Horizon oil spill settlement for erosion control.
