West Union Presbyterian Church is a historic congregation of the Presbyterian Church (U.S.A.) in the village of West Union on the southern edge of Ohio. Formed at the turn of the nineteenth century, it worships in an early nineteenth-century building constructed by a future governor of Kentucky, and it counted among its earliest members a governor of Ohio. The building has been named a historic site.

Thomas Metcalfe, also known as Thomas Metcalf or as "Stonehammer", was a U.S. Representative, Senator, and the tenth Governor of Kentucky. He was the first gubernatorial candidate in the state's history to be chosen by a nominating convention rather than a caucus. He was also the first governor of Kentucky who was not a member of the Democratic-Republican Party.
