The Hyland House Museum or Hyland–Wildman House is a historic house museum at 84 Boston Road in Guilford, Connecticut. Built in 1713, it is one of the town's best-preserved houses of that period. It has been open to the public as a museum since 1918, under the auspices of a local historic preservation group. It was added to the National Register of Historic Places in 1976.^[2] The house features Colonial-era furnishings and artifacts.

The Hyland House is located a short way east of Guilford's central town green, on the north side of Boston Street just east of Graves Avenue. It is a 2+1⁄2-story wood-frame structure, with a gabled roof, stone central chimney, and clapboarded exterior. Its main facade is five bays wide, with small-pane diamond-lighted windows arranged symmetrically around the center entrance. The entrance is simply framed, with a four-light transom window above. The rear roof face extends to the first floor, giving the house a classic New England saltbox profile. Its interior is noted for its decoratively chamfered girts, believed to be one an early example of this type of decoration.^[3]

The house has long been ascribed a construction date of about 1660, when builder George Hyland is thought to have built a house on this property.^[3] However, tree-ring dating conducted on its major timbers dates its construction to about 1713 or soon afterward, likely by the then-landowner, Isaac Parmelee.^[1] The house underwent an extensive restoration in 1917 by the architectural historian Norman Isham.^[3] The restoration was funded by the Society for the Preservation of New England Antiquities, now Historic New England.
