Grant Township was one of the original townships of Keweenaw County, which was organized in 1861. At the time, Grant Township occupied a much smaller centralized area of the county. The township soon expanded and absorbed the townships of Sibley and Copper Harbor, which are now defunct but can be seen on an 1873 map of Keweenaw County.
The Keweenaw Rocket Range, located within the township at the easternmost tip of the Keweenaw Peninsula, was used by NASA as a rocket launch site from 1964 until 1971.
