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

There were 2,018 housing units at an average density of 74.2 per square mile (28.6/km2).

18.9% of all households were made up of individuals, and 6.3% had someone living alone who was 65 years of age or older.

The journalistic organization ProPublica reports that during the mid-twentieth-century a Ground-to-Air Transmitter (GAT) Facility for the CIM-10 Bomarc system was located in Glenburn, supervised from Dow Air Force Base in Bangor for the Bangor Air Defense Sector.

Situated near to the current town offices, equipment and fuel storage facilities at the site contaminated the local groundwater to a degree that cleanup is expected to extend until the year 2039.
