Dun Glen (later Chafey) is a ghost town in Pershing County, Nevada, United States, 9 miles northeast of Mill City.

However its post office, opened on July 18, 1865 was called Dun Glen, and it operated as such until April 7, 1894.

[3] In 1863 the Sierra Mining district was formed 10 miles northeast of Mill City, with Dun Glen as its business center.

Chinese miners attempted drift mining of the gold laden placer gravels between 1880 and 1890 with limited success due to the water table.

On April 15, 1913, the post office closed with service transferred to Mill City, when mining operations ceased, and the population again declined and the town was again abandoned.
