Maple Grove Township was first established on October 28, 1909. It was set aside from the southern 36-square-mile (93 km) survey township area of Forest Township in the southeastern corner of Cheboygan County.

Although the township was created prior to the 1910 census, the new township went unreported in that decennial census. In the 1920 census, the population was recorded at 63. The township recorded a population of 33 in the 1930 census. In the 1940 census, the township recorded only 10 residents. Because of its very low population, the township returned back to Forest Township in 1942, at which time Maple Grove Township ceased to exist.

Although the township never had any precise area measurements, it occupied the southern 36 sections of Forest Township, which is a survey township area approximately equal to 36 square miles (93 km) total.

The township contained Dorsy Lake (or Duby Lake) and Silver Lake. The Black River also flowed through the township. The rural township had no major roadways, although M-33 was created in 1919 and ran near the eastern edge of the township.
