Jasper has been known as Coon Creek settlement, and as Midway (a name that at times included the Dublin community just across the Barton County line) for its position between county seats Carthage and Lamar, but in the late 19th century it was renamed Jasper to reuse the postal equipment of a previous Jasper that existed southeast of Carthage.

Jasper was the home to Debra Dene Barnes Miles the year after she finished her reign as Miss America (from 'Miss Kansas' title) in 1968.
