Walnut Grove Presbyterian Church

Walnut Grove Presbyterian Church is a historic church in rural Washington County, Arkansas. It is located southwest of Farmington, on the east side of Arkansas Highway 170. It is a modest single-story brick church, with a cross-gable roof and a squat square belltower. Each of its gable ends is adorned with a large three-part stained glass window. It was built in 1903 for a congregation established in 1856, and is a locally distinctive vernacular interpretation of the Romanesque Revival.

The church was added to the National Register in 1995.
