Township 2 South Range 10 West was first surveyed in January 1827 by Robert M. Clark. The first settler, William Tolland, came there in 1829 but apparently never purchased any land, despite living there for several years. In 1830, land entries were recorded for William Harris for the southwest quarter of section 17 and Major G. Van Dwyer for the southwest quarter of section 13 (the eastern portion of the section is now part of Galesburg). In 1831 land entries were recorded for Horace H. Comstock, Caleb Eldred, Thomas W. Merrill, Mumford Eldred, Stephen Eldred, Leland Lane, and others. Settling in the eastern part of the township in or near what is now Galesburg were Nathaniel Matthews, Ralph Tuttle, Sherman Cummings, George Townsend, and Nathan Cothren. H. H. Comstock, Caleb Eldred, and Cryus Lovell settled in the western part of the township near what became Comstock.

Comstock Township was organized by an act of the Territorial Legislature in 1834. Previously, it was a part of Arcadia Township (later renamed Kalamazoo Township), which initially comprised all eight townships in the northern half of Kalamazoo County. In June 1832, Richland Township was set off, consisting of Richland, Ross, Charleston, and Comstock townships. On March 7, 1834, Comstock township was set off, comprising Comstock and Charleston townships and also Climax Township, which had been set off from Brady Township. Climax was set off from Comstock on December 30, 1837, and Charleston in 1838.

Comstock Township became a charter township in 1964.
