Misery Mountain, 2,671 feet (814 m), with at least ten well-defined summits, is a prominent 6 mi (9.7 km) long ridgeline in the Taconic Mountains of western Massachusetts and adjacent New York.

It is notable for its views of the Hudson River Valley to the west.

The subordinate summits of Misery Mountain do not have names with the exception of the southernmost peak, 2,440 feet (740 m) referred to as Bill's Lunch in popular hiking guides.

Portions of the upper slopes and summit are within protected conservation land.

The southwest side drains into West Brook, Kinderhook Creek, thence the Hudson River; the southeast side into Kinderhook Creek.
