Alna is a town in Lincoln County, Maine, United States.

[3] Alna is home to the Wiscasset, Waterville and Farmington Railway Museum and is noted for its historic architecture, including the early mill village of Head Tide.

Originally a part of old Pownalborough, the town was settled around 1760 and incorporated in 1794 by the Massachusetts General Court as New Milford.

But residents did not like the name, so it was changed in 1811 to Alna, Latin for alder, the tree which grows in profusion along the banks of the Sheepscot River.

[4] Alna was the site of the first fish hatchery in Maine, started shortly after the Civil War.

Between 1895 and 1933, the narrow gauge Wiscasset, Waterville & Farmington Railway operated three stations in the town: Head Tide, Alna Center, and Sheepscot.

It borders the towns of Wiscasset to the south; Dresden to the west; Pittston, Whitefield and Jefferson to the north; and across the Sheepscot River, Newcastle to the east.

The racial makeup of the town was 99.56% White, 0.30% Native American and 0.15% Asian.
