The Pine Ridge School Building is a historic school building in rural Izard County, Arkansas. It is a single-story fieldstone structure, located on the south side of Pine Ridge Road (County Road 32) about 0.5 miles (0.80 km) west of Brockwell. It was built c. 1920, fashioned out of uncoursed native sandstone with grapevine mortar joints. A central gable-roofed entrance portico extends from the center of the building's north facade. It is a fine local example of an early 20th-century one-room school building.
