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