Enfield is a town in Penobscot County, Maine, United States.

[2] There is also a large seasonal population with many cottages located on Cold Stream Pond, a lake within the town.

Enfield was first settled on the east bank of the Penobscot River about 1820, and was originally called Cold Stream.

[3] In 1891, four armed men boarded and attempted to rob a train as it passed through Enfield, shooting at the engineer, fireman, and conductors.

They failed in their attempt to break into the mail-car, but it was a dark night and they escaped capture.

[1] Cold Stream Pond covers the eastern side of the town of Enfield.

There is a public boat launching facility on Old Hatchery Road off Maine State Route 188.

The southwestern corner of the pond overflows through Cold Stream, 5 miles (8.0 km) south to reach the Passadumkeag River 2 miles (3.2 km) upstream of the Penobscot River.

A self-sustaining native population of lake trout spawn in Webb Cove in the southeastern corner of the pond.
