The Mardot Antique Shop was a historic commercial building in the Columbia-Tusculum neighborhood of Cincinnati, Ohio, United States.

[2] Three stories tall, the building was a simple rectangle, two bays by three, and it featured a simple symmetrical facade with a cast iron front and many windows.

Other architectural features included multiple dormers in the roof (a mansard roof[1]), a small cornice with brackets, and a recessed portion of the storefront surrounding the main entrance.

[3] It was one of seventeen Columbia-Tusculum properties included in a multiple property submission related to a historic preservation survey conducted in the previous year; most of the properties were buildings, but the Columbia Baptist and Fulton-Presbyterian Cemeteries were also included.

[1] Despite this distinction, the Mardot Antique Shop has been demolished; the site is now an empty lot.
