Paiute cutthroat trout (Oncorhynchus clarkii seleniris) is one of fourteen subspecies of cutthroat trout. Paiute Cutthroat are native only to Silver King Creek, a headwater tributary of the Carson River in the Sierra Nevada, in California. This subspecies is named after the indigenous Northern Paiute peoples.[5][6]

Paiute cutthroat trout are endemic to and protected within the Carson Ranger District of the Humboldt-Toiyabe National Forest. The Carson River lies within the Great Basin interior drainage system, within the historic range of Lahontan cutthroat trout (Oncorhynchus clarki henshawi).

The biggest threats facing Paiute cutthroats include hybridization, nonnative fish, livestock grazing, and habitat fragmentation. Since most Paiute cutthroats are completely isolated, there is no genetic flow causing inbreeding, which leads to accelerated levels of extinction.[7]
