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 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.
