Nashville, often known as Music City, is the capital and most populous city in the U.S. state of Tennessee. It is the seat of Davidson County in Middle Tennessee, located on the Cumberland River. Nashville had a population of 689,447 at the 2020 census, making it the 21st-most populous city in the United States and the fourth-most populous city in the Southeast. The city is the center of the Nashville metropolitan area, home to 2.1 million people, and is among the fastest growing cities in the nation.

Named for Francis Nash, a general of the Continental Army during the American Revolutionary War, the city was founded in 1779 when this territory was still considered part of North Carolina. The city grew quickly due to its strategic location as a port on the Cumberland River and, in the 19th century, a railroad center. Nashville as part of Tennessee seceded during the American Civil War; in 1862 it was the first state capital in the Confederacy to be taken by Union forces. It was occupied through the war. After the war, the city gradually reclaimed its stature. It became a center of trade and developed a manufacturing base.

Since 1963, Nashville has had a consolidated city-county government, which is composed of six smaller municipalities in a two-tier system. The city is governed by a mayor, a vice-mayor, and a 40-member metropolitan council. Some 35 of the members are elected from single-member districts, while five are elected at-large. Reflecting the city's position in state government, Nashville is home to the Tennessee Supreme Court's courthouse for Middle Tennessee, one of the state's three divisions.

As of 2020, Nashville is considered a global city, type "Gamma" by the GaWC. The city is a major center for the music industry, especially country music. It is home to three major professional sports teams: the Predators, Titans, and Nashville SC. The city is also the home of many colleges and universities including Tennessee State University, Vanderbilt University, Belmont University, Fisk University, Trevecca Nazarene University, and Lipscomb University. Nashville is sometimes referred to as the "Athens of the South" due to the large number of educational institutions. The city is also a major center for the healthcare, publishing, banking, automotive, and technology industries. Entities with headquarters in the city include AllianceBernstein, Asurion, Bridgestone Americas, Captain D's, Concord, Gideons International, Hospital Corporation of America, LifeWay Christian Resources, Logan's Roadhouse, and Ryman Hospitality Properties.
