The Hopkins Mill District is a historic district in Foster, Rhode Island. It encompasses a historic mill village that extends along Old Danielson Pike between its two junctions with Danielson Pike (United States Route 6). The area has been the site of mills (at first grist- and sawmills) since the 18th century, and includes one of Foster's oldest houses, the c. 1720 Hopkins-Potter House at 21 Old Danielson Pike. Prominent public buildings in the district include the c. 1830 Curtis Hall at 18 Danielson Pike, which was long used as a tavern and social gathering place, and the 1869-71 Hopkins Falls Union Church.
