Duck Key is a census-designated place and unincorporated community in Monroe County, on an island in the middle Florida Keys. It sits oceanside of U.S. 1 near mile marker 61, between Conch Key and Grassy Key. The 2020 census counted 727 residents.
George Gauld named the island Duck Key on an 1775 chart, and salt ponds were worked here in the 1800s. The railroad bypassed it in 1912 and the rebuilt Overseas Highway bypassed it again after the 1935 hurricane. Developer Bryan W. Newkirk created the modern island in the 1950s. A wooden bridge opened in 1952 and the causeway opened to cars on January 2, 1953. He built five islands called Indies, Centre, Harbour, Plantation and Yacht Club, with about 10 miles of paved roads and four stone bridges.
Today the island is shared between Hawks Cay Resort and a residential community of 376 homes. The Duck Key Property Owners' Association, Club Duck Key and the Duck Key Security Advisory Board serve residents.
