The Christmas Mountains are a series of rounded peaks in northern New Brunswick, Canada, at the headwaters of North Pole Stream and the Little Southwest Miramichi River, west of Big Bald Mountain, and south of Mount Carleton. The mountains, in part, separate the Miramichi River watershed from the watersheds of the Serpentine River and the Nepisiguit River. In 1964, Arthur F. Wightman named the range and peaks after noting that the previously unnamed peaks lay near the source of North Pole Stream, hence this sub-range of the Appalachians has been named after the Christian holiday of Christmas.
