Historically, there was an Indian path leading through the Buckhorn area, and in what would become Buckhorn the path was blazed by the antlers of a deer in a white oak sapling. When the first non-native settlers arrived in the Fishing Creek valley, they created another path that intersected the Indian path, and the community came to be named for the deer antlers. The community was founded due to discovery of ore in the area. Vaniah Rees built the first house in the community in 1820. The first store in the community was opened in 1836. Mail was periodically brought to Buckhorn starting in 1850, but mail was not brought to Buckhorn on a daily basis until 1883.
