The Noisy-Diobsud Wilderness is a relatively small wilderness area in northwestern Washington state adjacent to North Cascades National Park.

Created in 1984, the Noisy-Diobsud contains 14,100 acres (57 km2) of steep valleys, subalpine lakes, and the summits of Anderson Butte and Mount Watson.

[1] It is part of Mount Baker National Forest.

The only maintained trail enters the west side of the wilderness from the Anderson Lakes road above Baker Lake.
