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 rein as Miss America (from 'Miss Kansas' title) in 1968. The city maintains a park at the west end of Grand Avenue just east of the railroad tracks. The park contains a playground for the children, a memorial bench, band stand, picnic areas, tennis courts and horse shoe pits. There is a baseball/softball complex on the southwest edge of town and are used by the youth baseball association and adult ball leagues.
Jasper Appreciation Days is held each September with events all week long ending with a huge celebration on the 3rd Saturday of the month.
Each November the city holds its annual Veterans Appreciation Celebration parade.
In the 1950s Jasper hosted a local fair celebrating its dairy industry. The current site of the popcorn plant was the PET condensed milk plant. The 1960s and 1970s were the years of the Jasper Harvest Fair held the last week before school started. The Chamber of Commerce sponsored a Kenny Carter Pit Bar-b-que. Hundreds would line up for bar-b-que brisket, chicken, baked beans, cole slaw, potato chips and bread. The evening was rounded off with local talent, the high school band and gospel singing groups. Jasper Appreciation Days is another celebration that takes place in early fall for two days. The Appreciation Days are filled with fun festivities. The Jasper student organizations use this to raise money for their affiliated organization, and to get their message out there.
