Fifth of July Mountain is a mountain summit located in the Entiat Mountains, a sub-range of the North Cascades, in Chelan County of Washington state. Fifth of July Mountain is situated in the Glacier Peak Wilderness, on land managed by Okanogan-Wenatchee National Forest. Its nearest higher neighbor is Chilly Peak, to the north-northwest, and Carne Mountain is set to the northwest. Precipitation runoff from the mountain drains west into Rock Creek which is a tributary of the Chiwawa River, or east into Cow Creek, a tributary of the Entiat River. This geographical feature was named by surveyor Albert Hale Sylvester for the day he visited it.
