The Henry Atchley House is a historic house in Dalark, Arkansas, a rural town in western Dallas County. It is located on County Road 249, just off Arkansas Highway 8. The two story wood-frame house was built in 1908 by Henry Atchley, who ran a general store in town. The house is basically vernacular in form, but has a number of stylish elements, including turned posts supporting a hip-roofed porch across the front, and a double-door entry with transom window. The front block of the house has a side-gable roof pierced by three gabled dormers, and there is a cross-gabled ell extended to the rear. The house was built in the economic boom associated with the arrival of the railroad and the community's subsequent economic success as a lumber town.
The house was listed on the National Register of Historic Places in 1983.
