The Stephen Decker Rowhouse is a historic multiple residence in the Columbia-Tusculum neighborhood of Cincinnati, Ohio, United States.

In 1869, after his death, Longworth's estate was platted and sold to builders who constructed a residential neighborhood along Tusculum Avenue.

One of the most unusual buildings was the Decker rowhouse, which features multiple distinctive Victorian elements.

Chief among these is the ornamentation on the porch roofs: they include gabled rooflines and beveled corners supported by multiple spindles.

Elsewhere, the houses feature double-hung windows, imbricated shingles on the gables, and arcades of Gothic Revival panelling, and numerous ornamental circles inscribed within squares.
