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.^[4]

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.

According to the U.S. Census Bureau, the township has a total area of 202.73 square miles (525.07 km²), of which 119.20 square miles (308.73 km²) is land and 83.53 square miles (216.34 km²) (41.20%) is water.

Grant Township is located at the northern end of the Keweenaw Peninsula along Lake Superior, and the township has the northernmost point of mainland in the state of Michigan. The township contains Fort Wilkins Historic State Park, and the community of Copper Harbor also provides the main ferry access to Isle Royale National Park via the Isle Royale Queen IV. The Montreal River flows through the township, and the township contains numerous lakes, most notably Lac La Belle, Lake Fanny Hooe, and a part of Lake Gratiot.

There are several lighthouses located within Grant Township, including Copper Harbor Light (and Copper Harbor Front Range Light), Gull Rock Light Station, Manitou Island Light Station, and Mendota (Bete Grise) Light.
