Lamoille Lake is a glacial tarn in the Ruby Mountains, in Elko County in the northeastern part of the state of Nevada. It is located at the head of Lamoille Canyon. It has an area of approximately 13.6 acres (5.5 hectares). It is a popular destination for day hikers and fishing, as the Ruby Crest National Recreation Trail passes its eastern shore before beginning a steep climb to Liberty Pass.
Lamoille Lake and Dollar Lakes are the principal sources of Lamoille Creek, which after exiting the mountains passes through the town of Lamoille, meanders down Lamoille Valley, and then merges with the main branch of the Humboldt River.
