March Rapids is an unincorporated community located in the town of Eau Pleine, Marathon County, Wisconsin, United States.

[2] In late 1892 Thomas March sold the mill to Doud & Sons, a barrel-making enterprise with factories in Winona, Rudolph and Pittsville.

The town grew to around 200 residents, with a general store, hotel, butcher, two saloons, shoemaker, blacksmith, dance hall, church and school.

[2] In 1905 the Wisconsin Central Railroad decided to pull up the tracks that had carried out March Rapids' products, despite Doud's objections.

[2] Today all that remains of Marsh Rapids is a park where County P crosses the Big Eau Pleine River, with a picnic area and a historical marker.
