Fountain County lies in the western part of the U.S. state of Indiana on the east side of the Wabash River. The county was officially established in 1826 and was the 53rd in Indiana. The county seat is Covington.

According to the 2020 United States Census, its population was 16,479. The county has two incorporated cities and six incorporated towns, as well as many small unincorporated communities. It is divided into eleven townships which provide local services. An interstate highway, two U.S. Routes and five Indiana state roads cross the county, as does a major railroad line.

Indiana was granted statehood near the end of 1816. The first non-indigenous settler in the future Fountain County is thought to have been a Mr. Forbes, who arrived in early 1823 and was soon followed by others. The legislative act creating Fountain County was passed on December 30, 1825, setting an effective date of April 1, 1826. The county's boundaries have remained unchanged since that time. It was named for Major James Fontaine of Kentucky who was killed at Harmar's Defeat (near modern Fort Wayne, Indiana) on October 22, 1790, during the Northwest Indian War.

The first Fountain County courthouse was a two-story frame building constructed in Covington in 1827; Abraham Griffith submitted the winning bid of $335. In 1829, plans were made for a larger courthouse building, but then an act of the legislature called for the county seat to be moved. In the end it was decided that the county seat should remain in Covington, and the brick courthouse was completed in 1833. A third courthouse was commissioned in 1856, and was completed in 1857 at a cost of $33,500. The circuit court met for the first time in the new building in January 1860, and the building was largely destroyed by fire the same day. Isaac Hodgson was the architect for the rebuilt courthouse, which was first occupied in January 1861; the total cost, including the reconstruction, totaled $54,624.05. The current courthouse was built in 1936–37 at a cost of $246,734; it replaced the previous building which had been declared unsafe. The 1937 building was constructed by the Jacobson Brothers of Chicago; the architects were Louis R. Johnson and Walter Scholar of Lafayette. The courthouse walls display murals painted by Eugene Francis Savage and others from 1937 to 1940, covering 2,500 square feet (232 m) of wall space and depicting the settlement of western Indiana.

Digging on the Wabash and Erie Canal began in 1832 and worked southwest; it reached Lafayette by 1842. In 1846 it reached Covington, and by 1847 traffic was moving through the county via the canal. Completion of the county's first railroad line in the 1850s heralded an end to the canal's usefulness, and in 1875 the last canal boat passed through Covington.

The first railway line through the county was the Toledo, Wabash and Western Railway (later the Wabash Railroad) which was built from the east across the northern part of the county and reached Attica in 1856; it continued west through Warren County and reached the Illinois state line the following year. The Indianapolis, Crawfordsville and Danville Railroad (later the Indiana, Bloomington and Western Railway), was started in 1855, but the general state of the economy halted construction in 1858. It was completed by another owner in 1870, and traffic started in 1871. It passed through Covington, Veedersburg and Hillsboro.

Fountain County's northern and western borders are defined by the Wabash River which flows southwesterly out of Tippecanoe County.

According to the 2010 United States Census, the county has a total area of 397.88 square miles (1,030.5 km), of which 395.66 square miles (1,024.8 km) (or 99.44%) is land and 2.22 square miles (5.7 km) (or 0.56%) is water. Elevations range from 770 feet (230 m) above sea level in the northeastern part of the county to 465 feet (142 m) in the southwest where the Wabash River leaves the county. The county is within the drainage basin of the Wabash River, sloping to the southwest. It is covered with loess ranging in thickness from a few inches to more than 7 feet (2.1 m). Approximately 84 percent of the county's land is use for agriculture.

The Portland Arch Nature Preserve and the Miller-Campbell Memorial Tract, a 435-acre (176 ha) preserve managed by the Indiana Department of Natural Resources, are located adjacent to the Wabash River.

US Route 136 follows the same general east–west route of I-74 through the county; in the eastern part it runs on the south side of the interstate, but crosses to the north side between Veedersburg and Covington. US Route 41 runs north–south through the county, passing through Attica and Veedersburg.

Three east–west state roads cross the county. State Road 28 enters Attica from Warren County and crosses the north end of the county. State Road 32 enters the middle of the county from Perrysville to the west and passes through Fountain County on its way to Crawfordsville to the east. State Road 234, further to the south, enters from Cayuga to the west and passes east through Kingman. Two north–south state roads run through the county. State Road 55 passes through Attica and shares the route of US Route 41 running goes south. At Rob Roy it turns to run southeast through Newton. State Road 341 starts at State Road 28 in the north and runs south, ending at State Road 234.

A Norfolk Southern Railway line crosses northern Fountain County on its route between Danville, Illinois and Lafayette, Indiana; it carries about 45 freight trains each day.

• Purdue University Airport - Indiana's second busiest airport, in Tippecanoe County, is operated by Purdue University.

The county government is a constitutional body granted specific powers by the Constitution of Indiana and the Indiana Code. The county council is the legislative branch of the county government and controls spending and revenue collection. Representatives are elected to four-year terms from county districts. The council members set salaries, the annual budget and special spending. The council has limited authority to impose local taxes, in the form of an income and property tax that is subject to state level approval, excise taxes and service taxes. In 2010, the county budgeted approximately $9.8 million for the district's schools and $3.2 million for other county operations and services, for a total annual budget of approximately $13 million.

A board of commissioners comprises the county's executive body. The commissioners are elected county-wide, in staggered four–year terms. One commissioner serves as president. The commissioners execute acts legislated by the council, collect revenue, and manage the county government.

The county maintains a circuit court. The judge on the court is elected to a term of six years and must be a lawyer admitted to practice law in Indiana.

The county has other elected offices, including sheriff, coroner, auditor, treasurer, recorder, and circuit court clerk. Each of these elected officers serves a term of four years and oversees a different part of county government. Members elected to county government positions are required to declare party affiliations and be residents of the county.

Each township has a trustee who administers rural fire protection and ambulance service, provides poor relief and manages cemetery care, among other duties. The trustee is assisted by a three-member township board. The trustees and board members are elected to four-year terms.

Based on the 2010 United States Census, Fountain County is part of Indiana's 4th congressional district; Indiana Senate district 23; and Indiana House of Representatives districts 13 and 42.
