Bourbon whiskey (; also simply bourbon) is a barrel-aged American whiskey made primarily from corn (maize). The name derives from the French House of Bourbon, although the precise source of inspiration is uncertain; contenders include Bourbon County, Kentucky, and Bourbon Street in New Orleans, both of which are named after the House of Bourbon. The name bourbon might not have been used until the 1850s, and the association with Bourbon County was not evident until the 1870s. it is associated with the Southern United States, particularly Kentucky, through a history of advertising bourbon as a product of Kentucky with rural, Southern origins. Thanks to a market shift in the 1990s, it has also become a symbol of urbanization and sophistication, with a large consumer demographic belonging to the middle- to upper-class, including business and community leaders.
Bourbon has been distilled since the 18th century. , distillers' wholesale market revenue for bourbon sold within the U.S. was about $2.7 billion, and bourbon made up about two thirds of the $1.6 billion of U.S. exports of distilled spirits.

Distilling was most likely brought to present-day Kentucky in the late 18th century by Scots, Scots-Irish, and other settlers (including English, Irish, Welsh, German, and French) who began to farm the area. The origin of bourbon as a distinct form of whiskey is not well documented and there are many conflicting legends and claims. For example, the invention of bourbon is often attributed to Elijah Craig, a Baptist minister and distiller credited with many Kentucky firsts (e.g., fulling mill, paper mill, ropewalk) who is said to have been the first to age the product in charred oak casks, a process that gives bourbon its brownish color and distinctive taste. In Bourbon County, across the county line from Craig's distillery in what was then Fayette County, an early distiller named Jacob Spears has been named as the first to label his product as Bourbon whiskey.
Although still popular and often repeated, the Craig legend is apocryphal. Similarly, the Spears story is a local favorite but is rarely repeated outside the county. There likely was no single "inventor" of bourbon, which developed into its present form in the late 19th century. Essentially, any type of grain can be used to make whiskey, and the practice of aging whiskey and charring the barrels for better flavor had been known in Europe for centuries. The late date of the Bourbon County etymology has led historian Michael Veach to dispute its authenticity. He proposes the whiskey was named after Bourbon Street in New Orleans, a major port where shipments of Kentucky whiskey sold well as a cheaper alternative to French cognac. It included the current Bourbon County in Kentucky, which became a county when Kentucky separated from Virginia as a new state in 1792. Numerous newspaper articles reference whiskey from Bourbon County, Kentucky dating as far back as 1824. According to the whiskey writer Charles K. Cowdery,
