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

It was first called T4 R4 NWP (or Township 4, Range 4, North of the Waldo Patent).

To encourage settlement, he gave away some land and built a combination gristmill and sawmill.

The town would be incorporated on December 11, 1816, as Corinna, named after Dr. Warren's daughter.

Corinna developed into a farming community, with water powered mills at the outlet of Corundel Lake.

After the arrival of the Dexter and Newport Railroad in 1865–1866, the village developed into a small mill town.

It resembles a mid-western county courthouse more than a typical small-town Maine library.

A memorial dedicated to the soldiers who have died in the War on Terror is located near the river.

Corinna is also located on the Newport/Dover-Foxcroft Rail Trail, which was developed along a former Maine Central Railroad line after tracks and ties were removed in 1993.
