Jefferson County is a county located in the Big Bend region in the northern part of the U.S. state of Florida. As of the 2020 census, the population was 14,510. Its county seat is Monticello. Jefferson County is part of the Tallahassee, FL Metropolitan Statistical Area but is the 3rd most rural county in Florida. There are no traffic signals within the entire county. During the plantation era, Jefferson County was the wealthiest per-capita county in the Florida territory.
In the mid to late 18th century, a group of Native Americans from Chiaha chiefdom settled in what is now Jefferson County. This group would eventually become an element of the Mikasuki speaking Seminole.
Jefferson County was created in 1827 from eastern Leon County. It was named for Thomas Jefferson, third president of the United States, who had died the year before the county's establishment.
In the two decades leading up to the American Civil War, cotton was the primary source of income in the county, with about seventeen percent of all Florida cotton being grown in Jefferson County. It was also the county with the second most large plantations (fifty-five plantations with thirty or more slaves) in Florida, behind only Leon County. In 1860, the county had a population of 9,876 with sixty-four percent being black. Following emancipation, the black population of Jefferson County continued to grow. By 1870 the population had risen to 13,968 with seventy-two percent black. To serve the relatively large black population in the county, the Freedmen's Bureau established an office in Monticello sometime around early 1866.
A fire destroyed most of the downtown wooden buildings in 1875, which were replaced by brick structures. Those that survived included the First Presbyterian Church and the Monticello News Building, the current home of Jefferson County’s newspapers. The Family Friend originated in February 1859. The Monticello News followed in 1909 and the Jefferson County Journal began publishing in July 2007.
Train service for passengers began in 1888, and tourists resulted in the St. Elmo hotel construction and the Perkins block which included a mercantile shop and general store on the first floor and a theater on the second. For two to six bits, guests could listen to live music, view a dramatic presentation or watch a circus. When passenger service ended in 1927, the tourism industry declined, as did the county population. The opera house slowed, then closed.
Jefferson Academy was established in 1852. The school building is referred to as the first built with bricks in Florida. Following the academy's closure, the building became Jefferson County High School. In 1890, Jefferson County operated 65 public schools including 30 white and 35 black which were segregated until 1965. The original Howard Academy was a black school that operated from 1936-1960 and is listed on the National Register of Historic Places.

Vernicia fordii (common name Tung Tree) is native to southern Asia but was introduced to US Gulf states in 1905. Tung oil is rendered from the seeds and used as a wood finish or an ingredient in varnish. During the 1950s, Jefferson County had more than 12,000 acres (4,900 ha) of tung trees and was the largest producer of tung oil in Florida and central to that industry in the state. Infrastructure for this major agricultural commodity included:
Freezes, hurricanes, synthetic chemical alternatives and foreign competition ended the tung oil industry in Florida between 1960 and the 1970s.
The Jefferson County Kennel Club (JCKC) was a greyhound racing venue established in 1958 and closed in 2014. It was the only dog track in north Florida between Jacksonville and Pensacola. The facility employed almost 300 local residents and made a significant contribution to the county's economy. A poker room was added in 2003 featuring Texas hold 'em and the track became a Racino. The cards became more profitable than dog racing, which ended in 2011.

According to the U.S. Census Bureau, the county has a total area of 637 square miles (1,650 km2), of which 598 square miles (1,550 km2) is land and 38 square miles (98 km2) (6.0%) is water.
Jefferson County is called the keystone county because it is the only county in Florida which borders both the state of Georgia and the Gulf of Mexico. It is also one of only five counties extending from the northern border of the state to the Gulf of Mexico. The other four are the four westernmost counties in Florida, which from west to east are Escambia, Santa Rosa, Okaloosa, and Walton counties, which all border Alabama.
The eastern border with Madison County is the Aucilla River. The start of the Wacissa River in the county's southeast is Wacissa Springs. The county extends across the Cody Scarp. The Woodville Karst Plain south of Monticello extends to the Gulf and contains numerous sinkholes and springs. The northwestern border with Leon County is the Red Hills Region of Tallahassee with rolling hills of red sand clay. Lake Miccosukee is a large, swampy prairie lake in northern part of the county.

Jefferson County, like most counties in the Florida Panhandle, historically voted for Democratic candidates. However, while most counties in the Panhandle started reliably voting for Republican candidates, Jefferson County has divided its support among Democratic and Republican candidates. From 2000 to 2012, while Democratic candidates for President won the county, the margin dwindled over time; in 2016, the county voted for Donald Trump, the first time that it had voted for a Republican presidential candidate since 1988. In 2020, Trump expanded his margin of victory. Jefferson County consistently backed Democratic candidates in statewide races, but in 2018, Ron DeSantis became the first Republican gubernatorial nominee to win Jefferson County since 1884. Donald Trump again increased his margin in 2024, winning the highest percentage of the vote for a Republican presidential candidate since Nixon in 1972.
