Frankfort is the capital city of the U.S. state of Kentucky. It is a home rule-class city and the seat of Franklin County. As of the 2020 census, the population was 28,602, making it the 13th largest city in Kentucky and 4th smallest U.S. state capital by population. Located along the Kentucky River in the Upland South, Frankfort is the principal city of the Frankfort, Kentucky micropolitan area, which includes all of Franklin and Anderson counties.
Before Frankfort was founded, the site was a ford across the Kentucky River, along one of the great buffalo trails used as highways in colonial America. English explorers first visited the area in the 1750s. The site evidently received its name after an incident in 1780, when pioneer Stephen Frank was killed in a skirmish with Native Americans; the crossing was named "Frank's Ford" in his memory. In 1786, the Virginia legislature designated 100 acres (40 hectares) as the town of Frankfort and, after Kentucky became a state in 1792, it was chosen as capital.
