The Charles A. Miller House is a historic residence in Cincinnati, Ohio, United States. Built in 1890 according to a design by Samuel Hannaford, it is a two-and-a-half story building constructed in the Gothic Revival style. A brick and limestone structure with a slate roof, its facade is dominated by courses of ashlar, plus battlements at the top, and a prominent portico at the entrance. The floor plan is that of a rectangle, two bays wide and four bays deep; the right portion of the building features a gable, while the battlements appear primarily on the left side. Structurally, the house is supported by a post and lintel construction, with the exterior courses of stones forming the lintels as well as horizontal bands around the building.
