The Chicopee River is an 18.0-mile-long (29.0 km) tributary of the Connecticut River in the Pioneer Valley, Massachusetts, known for fast-moving water and its extraordinarily large basin: the Connecticut River's largest tributary basin. The Chicopee River originates in a Palmer, Massachusetts village called Three Rivers as a confluence of the Ware, Quaboag and Swift rivers. It passes through Wilbraham, Ludlow, and the Indian Orchard neighborhood of Springfield.
