Smith County is a county in the U.S. state of Tennessee. As of the 2020 census, the population was 19,904.^[2] Smith County is located in the region of the state known as Middle Tennessee. Its county seat is Carthage.^[3] The county was organized in 1799 and is named for Daniel Smith, a Revolutionary War veteran who made the first map of Tennessee and served as a United States senator.

Smith County is part of the Nashville-Davidson–Murfreesboro–Franklin, TN Metropolitan Statistical Area.

Smith County was established in 1799 from a portion of Sumner County, and was named for Daniel Smith, a U.S. Senator and former Secretary of the Southwest Territory.^[1] The location of the county seat was hotly contested between Bledsoesborough (near modern Dixon Springs) and William Walton's ferry and tavern at the confluence of the Caney Fork and the Cumberland River. In 1804, voters chose Walton's site, and a town, named Carthage, was platted the following year.^[1]

Smith County was the site of a large saltpeter mine. Piper Cave, located near Monoville, contains the poorly preserved remnants of dozens of saltpeter leaching vats. Most saltpeter mining in Middle Tennessee took place during the War of 1812 and the Civil War, though the exact dates of this operation are unclear.^[4]

According to the U.S. Census Bureau, the county has a total area of 325 square miles (840 km²), of which 314 square miles (810 km²) is land and 11 square miles (28 km²) (3.4%) is water.^[5] The county is located in a transition area between the rugged Highland Rim to the east and the flatter Nashville Basin to the west. The Caney Fork has its confluence with the Cumberland River in Carthage; these are the primary waterways flowing through the county. Cordell Hull Dam on the Cumberland is located near Carthage.

The county formerly operated Pleasant Shade Elementary School, which closed in 2007, and Cox Davidson Elementary, which closed sometime in the 1950s.^[15] New Middleton Elementary was formerly PreK–8, while Gordonsville Elementary was formerly PreK–6. A realignment beginning with the 2017–2018 school year resulted in the current grade alignment of those schools.^[16]

Prior to 2008, Smith County was a Democratic Party stronghold at the presidential level. The county failed to back a Democratic candidate only twice between the Civil War and 2004, when voting for George Wallace in 1968 and against George McGovern in 1972. However, while the county was Carthage resident Al Gore's fourth strongest statewide in his 2000 presidential bid, he failed to win an increasingly Republican Tennessee. Democrat John Kerry won the county in 2004, but by a much narrower four point margin. Since then, Smith County has swung hard towards the Republican Party similar to the rest of the state outside of Memphis and Nashville. Hillary Clinton failed to win even a quarter of the county's votes in 2016, a far cry from the 71 percent and 62 percent her husband Bill won in the county with Gore also on the ticket.
