The Thomas Lynch House is a historic house in rural northern Searcy County, Arkansas. It is located down a private lane east of County Road 52, north of the Pine Grove Church. It is a single-story dogtrot, fashioned out of square-cut oak logs chinked with concrete, and topped by a metal roof. A porch extends across the front, supported by unfinished square posts, and a kitchen ell extending to the south is the only significant alteration.
