Copper Mountain Fire Lookout is a historic lookout tower in North Cascades National Park, built in 1934 in the former Glacier Ranger District of Mount Baker National Forest. Designed as a small square wood-frame cabin with broad windows, awning shutters, a shingled gable roof, and lightning rods, it was suited to an exposed mountaintop setting. In the winter of 1943, it also served a wartime function when the Aircraft Warning Service staffed it to watch for enemy aircraft. It is significant as one of only three Forest Service-era lookouts still standing in the park and was listed on the National Register of Historic Places in 1989.
