Gradyville is an unincorporated community in Adair County, Kentucky, United States.

[2] It was the birthplace of Western Kentucky University basketball coach Edgar Diddle.

[3] In February 1882, an Act of the General Assembly of the Commonwealth of Kentucky was approved that prohibited the sale of alcoholic beverages within one mile of Wilmores and Kemp's store-house in Gradyville.

[4] Gradyville suffered a flash flood on June 7, 1907, as the result of a cloudburst that precipitated three inches of rain in an hour.

The sudden downfall caused Big Creek, a normally small and quiet stream that runs through Gradyville,[5] to rise by ten feet and to wash away several houses that were built on the banks of the creek.
