Dancyville is an unincorporated community and census-designated place (CDP) in Haywood County, Tennessee, United States.

The community was properly established in 1837 by merchants Fennell T. Carpenter and John Sutherland.

The community was named after local blacksmith Isaac Dancy, who arrived in the area in 1831.

The first mention formal of the name Dancyville is found in the court minutes of March 1838, regarding a committee being formed to observe and work out a road from the Fayette County line through Dancyville to Brownsville.

In 1849 the Dancyville Female Academy was organized and began meeting in the local Masonic Lodge.
