Fountain Run is a home rule-class city in Monroe County, Kentucky, in the United States.

[3] Jamestown, located in Monroe County after 1820, appears in public records and on maps with this name through the Civil War.

"Jimtown" (diminutive of Jamestown) as a nickname for the town and community persisted after the new postal name of "Fountain Run" was created.

Famed musician Billy Vaughn from Glasgow, Kentucky composed (1968) the song, "The Jimtown Road", inspired by this historic Barren County route, which was recorded (1969) by The Mills Brothers, although the song's lyrics are mostly veiled references about Glasgow and Bowling Green, Kentucky, instead of Fountain Run.

[9] Jimtown Academy was established in 1897 in Fountain Run as a school of private instruction that included "primary and preparatory departments", with W. B. Robinson as principal.

[11] The Monroe County section of Kentucky: A History of the State (1886) includes brief biographies of some prominent 19th-century citizens of the Fountain Run community.

[12] Two booklets authored by local resident Lucy Albright (1903–1985) have been widely recognized as sources of the traditional history of Fountain Run and of genealogies of some early families of the community.

[1] Spring Creek runs along the eastern border of the city, and Jakes Branch drains the western part; both streams flow south to Indian Creek, just west of its mouth at the Barren River, part of the Green River watershed.
