Mount Lincoln is a 5,868-foot (1,789-meter) mountain summit located in the Olympic Mountains, in Mason County of Washington state, United States. It is situated on the boundary shared by Daniel J. Evans Wilderness and Mount Skokomish Wilderness, as well as the shared common border of Olympic National Park with Olympic National Forest. Lincoln is the second-highest point on Sawtooth Ridge, and the nearest higher neighbor is Mount Cruiser, 1.1 mi (1.8 km) to the northeast. Lincoln has two sub-peaks: a North Peak, and a Southwest Peak. Flapjack Lakes lie immediately west below the north sub-peak. Topographic relief is significant as the summit rises over 5,100 feet (1,600 m) above the Staircase Ranger Station at Lake Cushman in approximately two miles. Precipitation runoff from the mountain drains into tributaries of the North Fork Skokomish River, and partly into Mildred Lakes, thence Hamma Hamma River.
