The Swift River is a river in Massachusetts, United States. It has an east branch, a west branch, and a middle branch.[1] It is a tributary of the Ware River. Part of it is dammed in the Swift River Valley to form the Quabbin Reservoir serving Boston and Eastern Massachusetts.[2] Several towns were lost when the reservoir was constructed and filled.[3]

Swift River Reservation is located along the east branch.
The former Academy at Swift River was located in Plainfield, Massachusetts. It is now a drug addiction treatment facility.[4]
Letting Swift River Go, a picture book by Jane Yolen with watercolor illustrations by Barbara Cooney, describes the flooding of the valley to create the reservoir.
