The Lemhi Shoshone are a tribe of Northern Shoshone, called the Akaitikka, Agaidika, or "Eaters of Salmon." The name "Lemhi" comes from Fort Lemhi, a Mormon mission to this group. They traditionally lived in the Lemhi River Valley and along the upper Salmon River in Idaho. Bands were very fluid and nomadic, and they often interacted with and intermarried other bands of Shoshone and other tribes, such as the Bannock. Today most of them are enrolled in the Shoshone-Bannock Tribes of the Fort Hall Reservation of Idaho.
