The William Stone House is a historic house at the southeastern corner of the junction of Arkansas Highway 306 and Doris Lane in Colt, Arkansas. It is a -story wood-frame structure, roughly in an L shape. One leg of the L is on the right side, with a front-gable roof, extending south from the highway. Set slightly back from the front of this section, the second leg of the L extends east, with a hip roof and a porch extending its width with six Tuscan columns for support. The house is a fine local example of Plain Traditional architecture with Folk Victorian and Colonial Revival flourishes.
The house was listed on the National Register of Historic Places in 1992.
