Alfred I. DuPont Building, Art Deco skyscraper in Downtown Miami, United States

The Alfred I. DuPont Building is an Art Deco skyscraper in downtown Miami with 17 stories, marble and limestone walls, hand-painted ceilings, and streamlined moderne design elements. The structure displays ornate details and functional elegance throughout its floors from that era.

The Alfred I. DuPont Building was begun in 1937 and completed in 1939, replacing the Halcyon Hotel on the site. It was the first skyscraper raised in Miami after the 1928 county courthouse and the bust, and it marked the city's emergence from the Great Depression. Alfred I. DuPont, owner of the Florida National Bank, was its principal tenant. It was listed on the National Register of Historic Places on January 4, 1989.

The building is named for Alfred I. DuPont, owner of the Florida National Bank, its principal tenant. In 2023 its major tenants are bench jewelers who make and repair jewelry, and a firm that manufactures and wholesales watches for Rolex and Richard Mille. Miami's other jewelry building is the Seybold Building.

The Alfred I. DuPont Building stands at 169 East Flagler Street in downtown Miami, within the Downtown Miami Multiple Resource Area. The 17-story tower is a working jewelry and watch building rather than a museum, so visitors come for its bench jewelers and watch wholesalers. Enter from Flagler Street; the address is the reliable reference point for orientation.
