The Pawtucket Armory is an historic armory building at 172 Exchange Street in Pawtucket, Rhode Island. One of the major works of William R. Walker & Son, it was built in 1894–5. Built of red brick with granite and limestone trim, it has a distinctive main block, with crenellated towers at the corners, and is prominently sited near Pawtucket's central business district. It has a Richardsonian Romanesque entry, recessed under a round archway with wrought iron gates. The armory drill hall extends to behind the building along Fountain Street.
