Siesta Key is a barrier island off of the central western coast of Florida in the United States of America. It is situated between Sarasota Bay and the Gulf of Mexico. A portion of it lies within the city boundary of Sarasota, but the majority of the key is a census-designated place in Sarasota County. After the probable Amerindian name of Zarazote for the area and the bay, the key was originally named Sarasota Key by European cartographers during exploration beginning in 1513. That name can be seen on maps from the early 1700s as well as on all local maps drawn before the name change to Siesta Key in the 1920s. The population was 7,150 at the 2000 census.
