The Popham Colony—also known as the Sagadahoc Colony—was a short-lived English colonial settlement in North America. It was established in 1607 by the proprietary Plymouth Company and was located in the present-day town of Phippsburg, Maine, near the mouth of the Kennebec River. It was founded a few months after its more successful rival, the colony at Jamestown. That colony was established on May 4, 1607 by the London Company in present-day James City County, Virginia.
