Icicle Creek is a stream in the U.S. state of Washington. It originates at Josephine Lake near the crest of the Cascade Range and flows generally east to join the Wenatchee River near Leavenworth. Icicle Creek's drainage basin is mountainous and mostly undeveloped land within the Wenatchee National Forest and the Alpine Lakes Wilderness. The final of the creek are moderately developed with scattered homes and pasture, a golf course, children's camp, a small housing development called Icicle Island Club, and the Leavenworth National Fish Hatchery. Some water is diverted from the creek for municipal use by the City of Leavenworth at Icicle Creek river mile 5.6. Near Leavenworth, the wheelchair-accessible Icicle Creek Nature Trail, a National Recreation Trail designated in 2005, runs along a historic creek channel.
