Sumner County is a county located in the U.S. state of Tennessee. As of the 2010 census, the population was 160,645. Its county seat is Gallatin, and its largest city is Hendersonville. The county is named for American Revolutionary War hero General Jethro Sumner.
Sumner County is part of the Nashville-Davidson–Murfreesboro–Franklin, TN Metropolitan Statistical Area.
Sumner County was created in 1786, when Tennessee was still part of North Carolina. The county had been inhabited by Native Americans for centuries, as evidenced by Mississippian period mounds still visible at Castalian Springs. Longhunters traveled to the area as early as the 1760s, following Indian paths through the area. By the early 1780s, several outposts had been erected, most notably Mansker's Station, built by Kasper Mansker at modern Goodlettsville, and Bledsoe's Station, built by Isaac Bledsoe at Castalian Springs.
According to the U.S. Census Bureau, the county has a total area of 543 square miles (1,410 km2), of which 529 square miles (1,370 km2) is land and 14 square miles (36 km2) (2.5%) is water.
Sumner County is located in Middle Tennessee on the state's northern border with Kentucky. The Cumberland River was important in early trade and transportation, as it flows into the Ohio River to the west. Sumner County is in the Greater Nashville metropolitan area.
