History
New Haven was laid out and platted in 1815. Like many other towns in the Firelands region of Ohio that was settled by former residents of New England who fled the region during the American Revolutionary War, New Haven is named for the Connecticut city of the same name.

In 1833, New Haven contained three stores, two taverns, two physicians, and one tin factory.

New Haven is one of the ending points for what has come to be known as the "Old State Road" or the "Worthington-New Haven Road", an old route that connected this town and the Firelands area to Worthington and subsequently the capital city of Columbus. The Old State Road (not to be confused with current Huron County Road 52, also known as Old State Road), follows present day State Route 598 south to Galion.
