Lincoln Peak, Mountain summit in Washington, United States.

Lincoln Peak is a subsidiary summit of Mount Baker in the Cascade Range, within Mount Baker Wilderness and Mount Baker-Snoqualmie National Forest. At over 9,080 feet (2,770 m) it is Washington's 16th-highest peak, though its prominence is only 720 feet (220 m). Lincoln, Colfax and Seward Peaks are erosional remnants of an older eruptive episode, while the nearby Mount Baker cone comes from more recent volcanism.

Lincoln, Colfax and Seward Peaks are erosional remnants of an older eruptive episode of the Mount Baker volcanic system; later activity built the nearby Mount Baker cone. Lincoln Peak stands 0.6 miles (1 km) west-southwest of the higher Colfax Peak, and its own prominence is only 720 feet (220 m).

Lincoln Peak is one of three erosional remnants, with Colfax and Seward Peaks, left from an older eruptive episode of the Mount Baker volcanic system. The modern cone of Mount Baker formed later from more recent activity. The peak's name links it to this volcanic history rather than to a separate mountain.

Ascending requires specialized equipment such as ropes, ice tools, and crampons for safe movement. Spring conditions typically provide more stable climbing opportunities compared to other seasons.

Lincoln Peak is an erosional remnant from an older eruptive episode of the Mount Baker volcanic system; the younger cone of Mount Baker itself lies nearby. Its prominence is only 720 feet (220 m), and the nearest higher summit is Colfax Peak, 0.6 miles (1 km) to the east-northeast.
