Directly across the hall from the parlor is the dining room. The mahogany-veneered paneled door has silver-plated knobs, hinges and escutcheons that French rescued from a demolished New York townhouse. Henry Bacon designed the fireplace mantel with its supporting engaged Tuscan columns. Concealing the entrance to the butler's pantry is an antique Spanish leather screen with brass finials acquired by French in 1910 at a New York auction.

On one of his many antique hunting jaunts, French bought the small Empire sideboard in nearby Housatonic for eight dollars. It was in such poor condition that his wife refused to have it in the house. In the Studio, under French's direction, the piece was restored within a week's time and then placed in the dining room.

Hanging above this sideboard is a portrait of the sculptor, painted sometime between August 1876, when French returned from Florence, and February 1878, when it was exhibited at the Corcoran Gallery of Art in Washington, D.C. It is by French's friend Benjamin Porter. In 1879, French, in return, modeled a bust of Porter.

An Empire Revival pedestal dining table in the center of the room expands to hold up to five leaves and was bought by French before 1900. The fourteen black-painted chairs were purchased by French's daughter in Spain in 1923 for her own residence on the Chesterwood grounds (known as "The Dormouse") and brought to Chesterwood in 1960.

French doors open onto the breakfast porch. As on the west porch, the exterior entrances are arched. Originally, within the east archway's trellised niche, Evelyn Beatrice Longman's polychrome bust Bacchante (1912), for which the artist's daughter was the model, was on view.
