Dancy-Polk House, Historic residence in Decatur, United States.

The Dancy–Polk House is a two-story frame residence in Decatur, Alabama, built in 1829 for Colonel Francis Dancy. Its double-height portico carries four Doric columns on each level, a Georgian form Dancy brought from southern Virginia. It is the oldest building in Decatur and one of only four to survive the Civil War.

Colonel Francis Dancy, an early settler from southern Virginia, built the house in 1829. It is the oldest building in Decatur and one of only four to survive the Civil War, alongside the Old State Bank, the Rhea–McEntire House and the Todd House. It was listed on the Alabama Register of Landmarks and Heritage in 1978 and the National Register of Historic Places in 1980.

The house is named for Colonel Francis Dancy, who built it in 1829, and for the Polk family, later owners. Dancy came from southern Virginia and built in the Georgian style of his home region, which is why the house differs from local building traditions. It is the oldest building in Decatur.

The house stands in Decatur, where it is the oldest surviving building and one of four that came through the Civil War. Visitors look at the exterior: a two-story frame with a double-height portico, four Doric columns on each level. It was listed on the Alabama Register in 1978 and the National Register in 1980.

The house is the oldest surviving building in Decatur; only three others in the city outlasted the Civil War: the Old State Bank, the Rhea–McEntire House and the Todd House in the Bank Street–Old Decatur Historic District. Colonel Francis Dancy, its builder, later left Alabama for Franklin, Louisiana.
