The Talcottville Historic District is a historic district in the town of Vernon, Connecticut. Centered on Elm Hill Road and Main Street, it encompasses a 19th-century mill village, including archaeological remnants of very early cotton-spinning facilities, and old stone dam, and a major wood-frame mill constructed by the Talcott brothers. Also included in the village are a significant number of mill worker housing units, many dating to the middle decades of the 19th century, and an 1891 lenticular pony truss bridge, built by the Berlin Iron Bridge Company. The district was listed on the National Register of Historic Places in 1989.
