Lena is a village in Oconto County, Wisconsin, United States.

Originally known as Maple Valley,[6] Lena owes its location to the railroads.

The first white family at the site that became Lena was the French-Swiss immigrant Étienne Clement Roserens together with his French-Canadian wife Vitaline née Tessier, who established a homestead in October 1872.

[7][8][9] Their daughter Anna Rosera Hendricks was the first white child born in the settlement.

Other early white settlers in this vicinity arrived in the late 1870s and consisted primarily of French Canadian immigrants.

As was common in other areas populated by French-Canadians during this era, most of the Maple Valley residents engaged in small-scale logging, concentrating their work and their homes along Jones Creek, a tributary of the Little River.

By 1879 the community had become large enough to support a post office and, since the name "Maple Valley" had already been assigned to another Wisconsin post office, the recommendation of a new name fell to Oconto Postmaster George R.

[6][10] Hall submitted the first name of his future wife (Helena "Lena" Louisa McCartney)[6][10][11] to the federal postmaster, and the choice was approved.

[12] According to the United States Census Bureau, the village has a total area of 1.03 square miles (2.67 km2), all of it land.
