The Pascoag Grammar School, also previously the Burrillville High School, is an historic school building at 265 Sayles Avenue in the Pascoag village of Burrillville, Rhode Island. The Colonial Revival school was built in 1917 by Thomas McLaughlin and Mahoney & Coffey to replace a previous school that had burned. There had been a school on the site since at least the mid-19th century. The school is a T-shaped brick structure 2-1/2 stories high. It has fifteen bays across its main facade, with a raised center entrance. When built it first served as the town's high school. In 1936 a new high school building was built, and this one the served strictly as an elementary school until it was closed in 1995. It sat vacant until 2005, when it was acquired by a developer and rehabilitated.
