It was established as the district of Stoughtonham on June 21, 1765, incorporated as the Town of Stoughtonham on August 23, 1775, and was named Sharon on February 25, 1783, after Israel's Sharon plain, due to its high level of forestation. Several towns in New England were given this name. Part of Stoughtonham went to the new town of Foxborough on June 10, 1776. During the American Revolution, the townspeople of Sharon made cannonballs and cannons for the Continental Army at a local foundry.
