Mainflingen is one of the two constituent communities of Mainhausen, the other one is Zellhausen.

Mainflingen was first mentioned in a document from the year 775. In this and other documents from 793, 796 and 799 it is confirmed that citizens of the municipality Manolfingen bequeathed fields and meadows to the monastery Lorsch. Researchers believe that the name is not derived from the river Main, but from a man named Manolf and his ancestors.

A document confirms that Witch-hunts also occurred in Mainflingen.

As a direct consequence of the Thirty Years' War, Mainflingen and the surrounding communities had suffered severe population losses.
