Deadman Lake is a lake near the northern edge of Uintah County, Utah, United States.
The lake, elevation , is located in the Uintah Mountains within the Ashley National Forest at the western foot of Mount Untermann. A stream which flows west down the western face of Mount Untermann and Deadman Lake constitute the headwaters of Dry Fork (which flows in southeast and into Ashley Creek, at a point east of Steinaker Reservoir).
Deadman Lake was named in memory of a man who died of exposure at the lake while spending the winter there.
