Jacksonville Beach, also referred to locally as "Jax Beach", is a city in Duval County, Florida, United States.

Like the other towns, it maintains its own municipal government but its residents vote in the Jacksonville mayoral election and have representation on the Jacksonville city council. The population was 20,990 at the 2000 census. As of 2005, the population estimate by the U.S. Census Bureau is 21,770 blank">http://www.census.gov/popest/cities/files/SUB-EST2005-all.csv, giving the city a population density of 2,827/mi² (1,094/km²).
Although the French Huguenots led by Captain _Jean Ribault laid claim to the First Coast in 1562, it was the Spanish who first settled the Jacksonville Beach area, establishing missions from Mayport to St. Augustine. The Spanish ceded East Florida to the English by treaty in 1763 only to regain control twenty years later. In 1821 the Spanish ceded Florida to the United States of America. The Jacksonville Beaches area has been inhabited since at least 1837 when Mayport was made a port, but it was not until 1883 that the Jacksonville and Atlantic Railroad established "Ruby Beach" in modern-day Jacksonville Beach. The settlement was renamed "Pablo Beach" three years later, and was incorporated as a town in 1907. The name was changed to "Jacksonville Beach" in 1925.
Jacksonville Beach is the largest town in the Jacksonville Beaches community. It is the eastern terminus of U.S. Route 90, which ends at an intersections with State Road A1A three blocks from the Atlantic Ocean.
