The Mayo House is a historic house at 302 Elm Street in Marvell, Arkansas. It is a 1+1⁄2-story wood-frame structure, clad in novelty siding, with a dormered hip roof. It was built in 1917 by H. B. Mayo, the developer of this residential subdivision, and occupied by his family 1917–20. The house is a locally distinctive rendition of Colonial Revival styling, with some Craftsman features. The east-facing front has a full-width single-story porch which wraps around to the north side, and is supported by seven fluted metal columns.
