The former Morrilton Post Office is a historic post office building at 117 North Division Street in downtown Morrilton, Arkansas. It is a single-story masonry structure, built of brick and limestone in a simplified Art Deco style. Its facade is divided into five bays, the outer two separated by brick piers from the inner three. The inner three are articulated by limestone pilasters, and feature large multipane windows and the main entrance. The interior features a mural entitled "Men at Rest" by Richard Sargent, painted in the 1930s as part of a federal works project.
