Nininger Township was organized in 1858, and named after the village of Nininger, Minnesota. In 1857 Nininger was the site of the first recorded organized baseball club in Minnesota. They proposed extending a challenge to the "whole west" in a game of baseball. All that currently remains of the city of Nininger are a few buildings dedicated to township management and two historical markers.
