Arcadia is a city and county seat of DeSoto County, Florida, United States. Arcadia's Historic District is listed on the National Register of Historic Places. Its population was 7,420 as of the 2020 census. 
 According to The Atlas of Florida, "The Rev. James Madison ("Boss") Hendry (1839–1922) named the town in honor of Arcadia Albritton (1861–1932), a daughter of Thomas H. and Fannie (Waldron) Albritton, pioneer settlers. Arcadia had baked him a cake for his birthday, and he appreciated it so much that he named the city after her."
 In 1886, transportation improved in Arcadia when the Florida Southern Railway (later the Atlantic Coast Line Railroad) was built through Arcadia on its way from Bartow to Punta Gorda. The railway caused Arcadia to grow significantly, which led to it becoming incorporated a year later. A second railroad line, the Charlotte Harbor and Northern Railway (later the Seaboard Air Line Railroad), was built through Arcadia from 1907 to 1910 on its way from Mulberry to Boca Grande. Both lines have since been consolidated into a single line by CSX with the Seaboard line surviving north of Arcadia and the Atlantic Coast Line surviving to the south. Arcadia was also served by the short-lived East and West Coast Railway, which connected Arcadia with Bradenton from 1915 to 1934.
 During the late 19th century Arcadia was the county seat of what would become many counties. In 1921, legislation enacted called for Arcadia to remain the county seat of DeSoto County and resulted in the creation of the present-day counties of Charlotte, Hardee, Glades and Highlands. Prior to this breakup, Arcadia's population had grown considerably, with over 1,000 permanent residents and 3,000 sq mi (7,800 km2) for ranching.
 On Thanksgiving Day in 1905, the town was destroyed by a large-scale fire that originated from a midtown livery stable. The fire was exacerbated because the town did not have a working water system or fire department. The estimated monetary damage was $250,000, but no loss of life occurred. Much of the business district was not spared. The town recovered only years later.
 Oak Street is the "main street" in Arcadia. The downtown is far more elaborate than neighboring counties' downtown areas, as Arcadia is older and was their county seat prior to the formation of their present counties. Arcadia is also home to many early 20th-century homes, houses of worship, and several historic public buildings.
 From 1917 to 1922, Arcadia was the home of Carlstrom Field, a grass airfield of the U.S. Army Air Service named for deceased aviation pioneer Victor Carlstrom. Carlstrom Field was used for pilot training both during and after World War I. In May 1941, the site again became an airfield for military primary flight training, operated by the Embry–Riddle Aeronautical Institute (now Embry–Riddle Aeronautical University). Carlstrom Field, one of several satellite fields in the Fort Myers area, also trained pilots for the Royal Air Force until its closing in 1945.
 Arcadia's historic buildings include the Johnson-Smith House, William Oswell Ralls House, and Micajah T. Singleton House. Also, around 3,400 acres, which includes the downtown area, are part of the Arcadia Historic District.
 After three Arcadia children, the Ray brothers, were diagnosed with HIV in 1986, school officials refused to let them attend school.  The Ray family won a $1.1 million judgement against the county school system, but were forced to leave Arcadia after their home was burned down in 1987.
 In 2004, Arcadia was heavily damaged by Hurricane Charley, during which the eye went over the city, with winds measured up to 109 mph (49 m/s) at 5:27 pm. The winds were suspected to be stronger outside the city, but cannot be proven due to the lack of equipment outside the city. The city's only shelter, the Turner Agri Civic Center, was a shelter made to withstand winds over 100 mph (45 m/s), but it collapsed during the storm. Everyone evacuated into the hallways and the kitchen of the Turner Center prior to the collapse. The people in the Turner Agri Civic Center were evacuated to DeSoto High School, but soon, part of its roof collapsed. In the center of the town, the Old Opera House's roof was peeled off, causing severe water damage. The hurricane severely damaged downtown, especially businesses on Oak Street and Polk Street. Eventually, the Red Cross shelter was forced to evacuate due to the collapsing of the building. The city water tower crumpled along Florida State Road 70 and was never replaced after the hurricane. The city's only hospital was heavily damaged, with 35 windows shattering. Part of the roof peeled back, which exposed equipment and patients to the wind-driven rain. This caused an estimated $2.3 million in damages to the hospital. Hurricane Charley caused 3,600 homes to be destroyed or heavily damaged, and displaced 16,000 people. The exact amount of damage is not known, but it was ln the millions of dollars. Two people died in DeSoto County during the storm, and 150 people were injured. Many residents of the town left and never came back.  
 After Hurricane Charley, the people in DeSoto High School were taken to the middle school nearby, where at least 75 people spent the night in the middle school's gymnasium. The hurricane caused downtown to be heavily damaged. The storm caused 90% of homes in DeSoto County to be damaged and 60% to be uninhabitable or destroyed. The National Guard was deployed to the city and started the cleanup process and enforced a strict curfew in the city. The people of Arcadia came together and started helping each other after the storm, from feeding people to rebuilding. Although during the rebuilding process, the first wave of the Great Recession began, the people of Arcadia were able to rebuild their homes and bring new homes to the city. Downtown Arcadia was rebuilt, but some parts of the county are still damaged from Hurricane Charley. About 12 years were needed to rebuild, but parts of the city and county are still damaged from it. 
 In 2017, Hurricane Irma went over the city as a category 1 hurricane. It did not cause a huge amount of damage to the city. Some of the downtown area was damaged, with the Oak Park Inn taking considerable damage, and was not able to open for 4 months after the storm. Parts of DeSoto County were flooded, especially communities on the Peace River. The storm dropped 10-15 in of rain near Morgan Park on the Peace River. The river and its tributaries flooded roadways, homes, and parks. The damage extent is unknown.  
 In March 2020, Arcadia declared a local state of emergency in response to the COVID-19 pandemic. DeSoto county has had 10,174 cases of COVID-19.
 On September 28, 2022, Hurricane Ian Made Landfall near Cayo Costa. The Hurricane struck as a strong Category 4 Hurricane, near Category 5 strength. The storm would go over the city of Arcadia as a Category 3 Hurricane. The Hurricane would cause major flooding along the Peace River, flooding homes and roads near or on the river. SR-72 collapsed, and buildings and homes in Arcadia would be damaged.
