Deadwood Peak is a summit located on the eastern border of Mount Rainier National Park. It is also on the shared border of Pierce County and Yakima County in Washington state. Deadwood Peak is situated on the crest of the Cascade Range, immediately north of Yakima Peak and Chinook Pass, with the Pacific Crest Trail traversing its east slope. Its nearest higher peak is Naches Peak, to the southeast. Deadwood Peak takes its name from Deadwood Lakes and Deadwood Creek to its northwest, and their names came from the large number of downed trees in the area. From Chinook Pass, a short scramble up the south side leads to the summit with unobstructed views of Mount Rainier.
