Fisher Island is a census-designated place in Miami-Dade County, Florida, United States, located on a barrier island of the same name. As of 2015, Fisher Island had the highest per capita income of any place in the United States. The CDP had only 218 households and a total population of 467.
Named for automotive parts pioneer and beach real estate developer Carl G. Fisher, who once owned it, Fisher Island is three miles off shore of mainland South Florida. No road or causeway connects to the island, which is accessible by private boat, helicopter, or ferry. Once a one-family island home of the Vanderbilts, and later several other millionaires, it was sold for development in the 1960s. The property sat vacant for well over 15 years before development began for very limited and restrictive multi-family use.
Fisher Island was separated from the barrier island which became Miami Beach in 1905, when Government Cut was dredged across the southern end of the island. Construction of Fisher Island began in 1919 when Carl G. Fisher, a land developer, purchased the property from businessman and real estate developer Dana A. Dorsey, southern Florida's first African-American millionaire. In 1925 William Kissam Vanderbilt II traded a luxury yacht to Fisher for ownership of the island.
