Stone County is located in the Ozark Mountains in the U.S. state of Arkansas. The county is named for the rugged, rocky area terrain of the Ozarks. Created as Arkansas's 74th county on April 21, 1873, Stone County has two incorporated cities: Mountain View, the county seat and most populous city, and Fifty-Six. The county is also the site of numerous unincorporated communities and ghost towns.

Most of the county is sparsely populated forested Ozark hills; including the northern fifth of the county managed by the United States Forest Service as the Ozark National Forest. The remainder of the county is used for poultry, ranching, and timber production. The White River runs along the eastern boundary of Stone County. The county contains six protected areas in addition to the Ozark National Forest: Blanchard Springs Caverns within the Ozark National Forest, two Natural Areas, two Wildlife Management Areas and the Ozark Folk Center, which preserves and interprets Ozark cultural heritage, especially traditional mountain folk music and crafts. Other features such as log cabins, one-room school houses, community centers, and museums, as well as annual cultural events, preserve the history and culture of Stone County.

Stone County occupies 609.43 square miles (1,578.4 km) and contained a population of 12,359 as of the 2020 Census.

Stone County is located in the Ozark Mountains, one of the six ecoregions of Arkansas. The Ozarks are a mountainous subdivision of the U.S. Interior Highlands, and Stone County contains the Springfield Plateau, Salem Plateau, and the relatively steeper Boston Mountains subsets. The county is roughly split along an east–west line near Mountain View, the centrally located county seat, with areas north within the Springfield Plateau, and areas south within the Boston Mountains. Areas along the White River, which forms the county's northeastern boundary, are dissected bluffs of the Salem Plateau rather than riparian floodplains. According to the U.S. Census Bureau, the county has a total area of 609.43 square miles (1,578.4 km), of which 606.59 square miles (1,571.1 km) is land and 2.84 square miles (7.4 km) (0.5%) is water.

The county is located approximately 105 miles (169 km) north of Little Rock, 151 miles (243 km) northwest of Memphis, Tennessee, and 278 miles (447 km) southwest of St. Louis, Missouri. Stone County is surrounded by three Ozark counties, Searcy County to the west, Baxter County to the northwest, Izard County to the northeast, and three border counties with the Arkansas River Valley, Van Buren County to the southwest, Cleburne County to the south, and Independence County (which also contains a small piece of the Arkansas Delta) to the east.

The county government is a constitutional body granted specific powers by the Constitution of Arkansas and the Arkansas Code. The quorum court is the legislative branch of the county government and controls all spending and revenue collection. Representatives are called justices of the peace and are elected from county districts every even-numbered year. The number of districts in a county vary from nine to fifteen, and district boundaries are drawn by the county election commission. The Stone County Quorum Court has nine members. Presiding over quorum court meetings is the county judge, who serves as the chief operating officer of the county. The county judge is elected at-large and does not vote in quorum court business, although capable of vetoing quorum court decisions.

Property tax is assessed by the Stone County Assessor annually based upon the fair market value of the property and determining which tax rate, commonly called a millage in Arkansas, will apply. The rate depends upon the property's location with respect to city limits, school district, and special tax increment financing (TIF) districts. This tax is collected by the Stone County Collector between the first business day of March of each year through October 15 without penalty. The Stone County Treasurer disburses tax revenues to various government agencies, such as cities, county road departments, fire departments, libraries, and police departments in accordance with the budget set by the quorum court.

Two incorporated cities are located within the county. The largest city and county seat, Mountain View, is relatively centrally located in the oddly-shaped county. Mountain View's population in 2010 was 2,748, marking the first decennial decline since the 1960 Census. Fifty-Six has maintained a stable population under 200 since incorporation.

Stone County has dozens of unincorporated communities and ghost towns within its borders. This is due to early settlers in Arkansas tending to settle in small clusters rather than incorporated towns. For example, communities like Newnata had a post office and dozens of buildings at some point in their history. Other communities are simply a few dwellings at a crossroads that have adopted a common place name over time. Some are officially listed as populated places by the United States Geological Survey, and others are listed as historic settlements.

Townships in Arkansas are the divisions of a county. Each township includes unincorporated areas; some may have incorporated cities or towns within part of their boundaries. Arkansas townships have limited purposes in modern times. However, the United States census does list Arkansas population based on townships (sometimes referred to as "county subdivisions" or "minor civil divisions"). Townships are also of value for historical purposes in terms of genealogical research. Each town or city is within one or more townships in an Arkansas county based on census maps and publications. The townships of Stone County are listed below; listed in parentheses are the cities, towns, and/or census-designated places that are fully or partially inside the township.

Mountain View Airport is the only public owned/public use airport in Stone County. Also known as Harry E. Wilcox Memorial Field, the facility is a small, rural general aviation airport with 5,650 annual operations. Stone County also contains one private airfield. The nearest commercial service airport is Clinton National Airport in Little Rock.

Stone County is not served by any Interstate highways nor United States highways; the nearest access to the Interstate system is Interstate 40 (I-40) in Conway. Ten state highways serve the traveling public in the county, varying from short connector routes to long highways traversing the entire county. Highway 5 and Highway 9 are major north–south highways across the Ozarks; each crosses through the county through Mountain View. The two routes briefly form a concurrency, or overlap, between Mountain View and Allison.

Highway 14 is a major east–west highway across northern Arkansas, it crosses the county and connects Mountain View and Fifty-Six via an overlap with Highway 5 and Highway 9. Highway 87 connects the communities more directly along a winding alignment. Highway 66 has its eastern terminus in Mountain View, and runs west to Leslie in Searcy County, connecting Mountain View to US Highway 65 (US 65). Highway 263 connects several unincorporated communities in southwestern Stone County. Highway 382 serves as an access for Ozark Folk Center State Park. Highway 58, Highway 74, and Highway 110 pass through the county for a few miles on their way to other destinations.

The county also contains the Sylamore Scenic Byway, an Arkansas Scenic Byway and National Forest Scenic Byway.

Entergy Arkansas is the sole provider of electricity in almost all of Stone County, with exceptions in the northern tip (served by North Arkansas Electric Cooperative), south of Mountain View (First Electric Cooperative) and the southwest corner (Petit Jean Electric Cooperative).

The Arkansas Department of Health (ADH) is responsible for the regulation and oversight of public water systems throughout the state. Stone County contains six community water systems: the City of Fifty-Six Water Department, the City of Mountain View Water Department, Pleasant Grove Water Association, Richwoods Water Association, Sylamore Valley Water Association, and the West Stone County Water Association. Mountain View has the largest direct retail population served (7,295, all in Stone County), followed by West Stone County (4,634, including customers served in adjacent counties), Pleasant Grove Water Association (2,315), and Richwoods Water Association (1,436), with the remaining systems under 600 retail population served. Of the water systems serving Stone County, only Fifty-Six uses groundwater, the Gunter Sandstone Aquifer, though also purchasing water from Big Flat, which pumps from the same aquifer. The City of Mountain View uses the White River, and the remaining systems purchasing treated water from Mountain View.
