Crooked Bum is the name of a 6,937 ft (2,114 m) mountain summit on the crest of the North Cascades in the U.S. state of Washington. It is located in the Okanogan National Forest on the shared border of Skagit County and Chelan County. It is situated immediately west of Rainy Pass and two miles east of Corteo Peak. The scenic and popular Maple Pass Trail traverses the south slope of the peak while staying above Lake Ann. Precipitation runoff from the north slope of Crooked Bum drains into Granite Creek which is a tributary of the Skagit River, whereas the south side drains into Bridge Creek which is a tributary of the Chelan River.
