John Endecott (before 1601 – 15 March 1664/5, also spelled Endicott) was an English colonial magistrate, soldier and the first governor of the Massachusetts Bay Colony. During all of his years in the colony but one, he held some form of civil, judicial, or military high office. He served a total of 16 years as governor, including most of the last 15 years of his life; this period of service was the longest of any colonial governor. He also held important posts representing the colony as part of the New England Confederation, and was a leading force in expanding the settlement of Salem, Massachusetts and other parts of Essex County.
