Revelo is an unincorporated community within McCreary County, Kentucky, United States.
Originally a railroad siding for Southern Railway (US) , the community was named for James Henry Oliver, an executive Vice President of Southern's Kentucky Division. Oliver was killed in a passenger train collision in 1918 in Danville, Virginia.
"Revilo" is "Oliver" spelled backwards. The United States Postal Service changed it to the modern spelling in 1943.
