About Dayville

Tucked into the town of Killingly in northeastern Connecticut, Dayville is a historic village set along the Fivemile River. It grew up as a bustling 19th-century mill community, and you can still see that heritage in the classic frame homes and vintage worker cottages that line its older streets. With Interstate 395 running right past the village and Routes 12 and 101 meeting nearby, it offers some of the easiest highway access in Windham County.

Dayville also serves as a convenient commercial hub for the surrounding area. You will find plenty of everyday shopping centers, local dining, and major employers like the regional Frito-Lay plant clustered near the main roads. Along with neighboring Danielson, Dayville provides a practical, down-to-earth base where you can handle daily errands with ease while enjoying the quieter pace of eastern Connecticut.
