About Menasha

Learn more about the host city, Menasha.

Menasha is a city located on former Menominee and Ho-Chunk territory in Winnebago and Calumet counties in the U.S. state of Wisconsin. The population was 18,268 at the 2020 census, of which 15,144 were in Winnebago County and 2,209 were in Calumet County. The city's name comes from the Menominee language, in which it is known as Menāēhsaeh, meaning "little island". At the time of European contact, a Ho-Chunk village known as "Menashay" stood on what is now Doty Island, led by Chief Hootschope. It is part of the Fox Cities region of Wisconsin. Doty Island is located partially in Menasha, which it shares with Neenah.
