The Shady Grove School is a historic school building on Arkansas Highway 94 near Pea Ridge, Arkansas. It is a single-story wood-frame structure, with a hip roof and a concrete foundation. A gable-roofed cupola provides ventilation to the roof, which is also pierced by a brick chimney. The main facade consists of a double door flanked by sash windows, and the long sides of the building have banks of sash windows. Built c. 1922, the building is a well-preserved representative of a period school building.
The building was listed on the National Register of Historic Places in 1988.
