Mount Raimer, , is a prominent peak in the Taconic Mountains of western Massachusetts and adjacent New York. The west side and summit are located in New York; the east slopes lie within Massachusetts. The summit ridge is part meadow and part wooded with red spruce, balsam fir, and northern hardwood tree species. It is notable for its views of the Hoosic River valley and Hudson River Valley. The Taconic Crest Trail traverses the mountain. Much of the upper slopes and summit are within protected conservation land. The mountain is the location of a defunct ski area.
