Wittenberg is a village in Shawano County, Wisconsin, United States.

In 1886, the Wittenberg Indian School was established by the Norwegian Evangelical Church of America after a purchase of land in Winnebago traditional territory.

Initial attempts to recruit students for the school were met with resistance, particularly from Winnebago "medicine men" who the missionaries believed were concerned about their intention to convert the children to Christianity.

[8] The school initially only taught a few children but eventually expanded to include over a hundred students who came from the Winnebago, Oneida, Stockbridge, Brothertown, Menominee, Mohawk and Chippewa.

[8] The school was sold to the government in 1900 and operated until 1917, when it was closed because of the First World War.

[6][8] After the closure of the federal school, the mission continued educating Native children, eventually educating up to 140 students with only four members of staff, as well as baptizing hundreds of local Native people.

[7][8] The high student to staff ratio was typical of overcrowded Indian schools, as documented by the Merriam Report.

[12] According to the United States Census Bureau, the village has a total area of 1.79 square miles (4.64 km2), all of it land.
