The Jackson Mountains are a north-northeast trending mountain range in southwestern Humboldt County, Nevada. The range is flanked on the west by the Black Rock Desert and the Black Rock Range beyond. To the north across the Quinn River and Nevada State Route 140 lie the Bilk Creek Mountains. To the northeast across Kings River Valley is the Double Mountains and to the east are the Sleeping Hills. To the southeast and south lie the Eugene and Kamma Mountains. The ghost town of Sulphur lies just southwest of the pass between the Jackson and Kamma ranges. Nevada State Route 49 and the Union Pacific railroad Feather River Route traverse this pass.
The range is typical of the Basin and Range Province with isolated high mountains surrounded by downfaulted basins filled with sediments. The rocks of the range include Paleozoic sedimentary and metamorphic rocks intruded by Mesozoic igneous rocks and covered by Mesozoic and Cenozoic volcanic rocks.
The highest peak in the range, reaching 9,099 ft (2,773 m), is known locally as Dan Dobbins Peak but has no official name. Other mountain peaks include:
