Dunnellon was founded in 1887,[1] two years before the 1889 discovery of phosphate in the area. It was officially incorporated as a city in 1891.[2] The subsequent mining boom, the first of its kind in Florida, lasted until the early 1910s.[7][8] The original mining took place in and around the Rainbow River (then called Blue Run,) using the river's natural flow to transport phosphates. One of the original mining pits is now called the 'Blue Cove' subdivision.[1] Phosphate industry operations began to shift south to the Polk County area, and by the 1960s, Dunnellon's last mine closed. Dunnellon survived the bust period, unlike other nearby phosphate towns including Romeo, LeRoy, Brewster, and Parkersburg.[8]
Areas in and around Dunnellon served as filming locations for the 2001 horror film Jeepers Creepers, with a great deal of location work on Tiger Trail (a.k.a. High School Road), the road to Dunnellon High School, officially known as SW 180th Avenue Rd., just outside Rainbow Springs State Park.
U.S. Route 41 passes through the city, leading north 24 miles (39 km) to Williston and south 18 miles (29 km) to Inverness. Ocala, the Marion county seat, is 24 miles (39 km) to the northeast.
