Swanville is a town in Waldo County, Maine, United States.

It was incorporated on February 19, 1818[3] (or 1819[4]), following a petition made in November 1816 by James Leach and 37 others.

[3][5] Late 19th century industries included farming, brick-making, soap-making, and quarrying.

[4] The Oak Hill Quarry opened in 1872, producing a dark blue-gray granite that was used for paving stones.

In 1979, an agreement was brokered between the towns of Swanville, Frankfort, Searsport and Goose River Hydro, Inc.

The agreement covers water levels as well as Goose River Hydro's responsibility for dam and land surrounding it.

In the late 19th century, the dam was operated by the Belfast Paper Mill Company and used only intermittently.

25.8% of all households were made up of individuals, and 7% had someone living alone who was 65 years of age or older.
