Kearsarge is an unincorporated community in Calumet Township, Houghton County in the U.S. state of Michigan.

[1] Kearsarge is served by a post office with ZIP code 49942, providing P.O.

It was named for the USS Kearsarge (1861) by a former naval officer who was an employee of the Calumet and Hecla Mining Company.

It had a station on the Hancock and Calumet Railroad (which became part of Duluth, South Shore and Atlantic Railway).

[4] During the Great Depression, workers with the WPA built a memorial to the 1862 naval ship out of stones, though the monument bears little resemblance to the sloop it commemorates.
