Criehaven is an alternative name for Ragged Island, an unorganized territory in Knox County, Maine, United States.

He and his wife, Harriet Hall (1829–1919), moved in 1849 to Ragged Island, where Robert became successful in farming and lumbering.

McLane asserts that after Crie's death, the "vigor of the community was gradually drained by natural disasters and changing times.

"[3] With its population dwindling, Criehaven plantation dissolved in 1925 to revert to a 'wild land' obviating the need for town meetings and further taxation.

After the school's closing, the accelerating departure of year-round families cost the island its general store and post office as well.
