The Great Miami Hurricane of 1926 was a large and intense tropical cyclone that devastated the Greater Miami area of Florida and caused catastrophic damage in the Bahamas and the U.S. Gulf Coast in September 1926, accruing a US$100 million damage toll. The devastation wrought by the hurricane resulted in the end of Florida's land boom, and represented an early start to the Great Depression in the state. It has been estimated that a similar hurricane would cause about $235 billion in damage if it were to hit Miami in 2018.

The Florida land boom of the 1920s was Florida's first real estate bubble. The economic prosperity of the 1920s coupled with a lack of knowledge about storm frequency and the poor building standards used by boom developers set the conditions for the first real estate bubble in Florida.
