Sharpsburg is a home rule-class city in Bath County, Kentucky, in the United States. The population was 323 as of the 2010 U.S. census. It is part of the Mount Sterling micropolitan area. Revolutionary War veteran Moses Sharp settled in the area in 1780 and laid out the town of Bloomfield on his land in 1814. After his death in 1820, the town received its first post office; since "Bloomfield" was preempted by another community, the postmaster named his station after Sharp, and the town was established and incorporated under this new name.
