The first inhabitants of the area known as Old Bridge were the Lenni Lenape Native Americans. Those who settled in Old Bridge and other parts of Central Jersey were known as the Unami, or "people down the river." They migrated to the shore along the Raritan each summer from their hunting grounds in the north. When the English gained control from the Dutch in 1664, the state was divided into two provinces, East Jersey and West Jersey. In 1683, the general assembly of East Jersey defined the boundaries of Middlesex County and the three other original counties (Bergen, Essex and Monmouth) as containing all plantations on both sides of the Raritan River, as far as Cheesequake Harbor to the east, then southwest to the Provincial line, with the southwest line being the border of Monmouth and Middlesex counties and the Township's southern border.
The Old Bridge Township post office opened in 1809, the earliest record of the town by name (U.S. post office records).
