Ebenezer Gay House, historic house museum in Sharon, United States

The Ebenezer Gay House is a 2+1⁄2-story brick building at 18 Main Street in Sharon, Connecticut, standing at the southern end of the town green opposite the First Congregational Church. Its west-facing facade is five bays wide, with a center entrance under a gabled porch on slender round columns, a side gable roof, end chimneys and a rubblestone foundation.

Ebenezer Gay built the house in 1775–76. He led the local militia during the American Revolutionary War and backed the war effort with his own money, which ruined him: he died insolvent in 1787 and the house was lost to foreclosure. Anne Hoyt bequeathed it to the Sharon Historical Society in 1951.

The house has been the Sharon Historical Society's museum since Anne Hoyt bequeathed it in 1951, and it holds the society's collections. The name Gay-Hoyt links the builder, Ebenezer Gay, with the later donor. The Federal-style porch on the west front, added around 1820, shows how the entrance was updated decades after construction.

The house stands at 18 Main Street, on the east side of the road at the southern end of Sharon's town green, directly opposite the First Congregational Church. The museum entrance is on the west-facing facade, reached through the gabled porch with round columns. The Sharon Historical Society, which occupies the building, holds its collections inside.

The interior maintains the original central hall floor plan with fireplace paneling and built-in cupboards dating to the 1700s. These details reveal the craftsmanship and materials that local workers used more than 2 centuries ago.
