South Beach, also nicknamed SoBe, is a neighborhood in the city of Miami Beach, Florida, United States. It is the area south of Indian Creek and encompasses roughly the southernmost 23 blocks of the main barrier island that separates the Atlantic Ocean and Biscayne Bay. This area was the first section of Miami Beach to be developed, starting in the 1910s, thanks to the development efforts of Carl G. Fisher, the Lummus Brothers, John S. Collins, and others.
