St. Pete Beach is a coastal city in Pinellas County, Florida, United States. Known as a tourist destination, St. Pete Beach was formed from the towns of Pass-a-Grille, Belle Vista, St. Petersburg Beach and unincorporated Pinellas County. At the time of its incorporation in 1957, its name was St. Petersburg Beach. On March 9, 1994, locals voted to officially change the name to the shorter version of St. Pete Beach, to distinguish it from the city of St. Petersburg a few miles to the east. The population was 9,346 at the 2010 census.
