Dublin, Missouri is a former community in Barton County, Missouri located on the Jasper County line approximately one mile north of the current town of Jasper. It was named after Dublin, in Ireland. Dublin and what is now Jasper were often referred to as Midway, but that moniker more properly referred to the Jasper County settlement. The main road through Dublin, later made part of the Jefferson Highway, continues south to become Main Street in Jasper.
