The area that Jenison occupies was first inhabited by Peoria and Odawa indigenous peoples, and later populated by white settlers in 1836 as a lumber site along the Grand River.
Jenison gained its name from the Jenison family's sawmill, which opened in 1864. A post office called Jenisonville was established in 1872, and the name was changed to Jenison in 1887.
