Cannonsburg is an unincorporated community and census-designated place (CDP) in Kent County in the U.S. state of Michigan.

[2] The community is within Cannon Township about 10 miles (16.1 km) northeast of the city of Grand Rapids.

While the area was still a part of Plainfield Township, the settlement at Cannonsburg was founded in 1842 on an old Native American trail (Chippewa and Ottawa populated the area prior to the region being opened for white settlers).

Bostwick, a business agent of railroad and steamboat financier LeGrand Cannon of Troy, New York, was instructed to give a lot to each resident who was not otherwise provided for.

Mention is made that the Michigan Legislature had organized the town under the name of "Churchtown" in the spring of 1846[8][9] (or 1845 in some sources[10]).
