Mendon was laid out a mile and a quarter from its current location in 1871 by Christopher Shupe. Shupe named it for his previous home place, Mendon, Illinois, which incorporated in 1867 and was named for Mendon, Massachusetts, incorporated precisely two centuries earlier, in 1667.
The Missouri area had been known as "Salt Creek", and businesses were in operation several years prior to the town plat actually being filed. Among the earliest was a general store built around 1865 by Mr. Bostich and Mr. Eastman. A Methodist church was erected in 1866. A sawmill was located five miles east of the town.
