Duck Key is a census-designated place and unincorporated community in Monroe County, Florida, United States, on an island of the same name in the middle Florida Keys. The CDP also includes the neighboring island of Conch Key. As of the 2000 census, the CDP had a total population of 443.

Duck Key is located oceanside of U.S. 1 (or the Overseas Highway), at approximately mile marker 61, between Conch and Grassy Keys at 24°46′32″N 80°54′39″W / 24.775623°N 80.910972°W / 24.775623; -80.910972.

The key was the site of a salt manufacturing operation in the 1820s & 1830s. Occupation of the island ceased after the Labor Day Hurricane of 1935 and did not resume until the key was connected to the highway by a causeway in 1953. J.W. Norie, in his Piloting Directions for the Gulf of Florida, The Bahama Bank & Islands (1828) states: "Duck Key - Some two miles (3 km) long, low, rocky, & covered with mangroves; some small patches of good land with a little timber. This island formerly saltworks but they were transferred latterly to Key West, owned by Mr. Howe, who is also possessor of this Key."
