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

[2] One of the largest water powered sawmills then on the Penobscot River was built in Medway in 1820 by Gen. Boyd, who owned half the township.

A second large mill was built soon after near what is now Medway Center, attracting settlers.

Boyd originally incorporated the town as "Kilmarnock", but the name was changed to Medway in 1854.

[1] The town is at the confluence of the East and West Branches of the Penobscot River.

At the 2010 census there were 1,349 people, 576 households, and 400 families living in the town.

At the 2000 census there were 1489 people, 587 households, and 437 families living in the town.

The Congregational Church of Medway (1874), designed and built by Mansford Cushman, is listed on the National Register of Historic Places.
