Waltham is a town in Hancock County, incorporated on January 29, 1833 from the township Number 14 MD, BPP. It ceded land to Eastbrook in 1872.
Waltham was first settled in 1804 when all travel was by boat or canoe on the Union River, which flows through Graham Lake that has long frontage in the town.
Maine Route 179 parallels the east side of the Lake and 200 connects the community to Eastbrook.
