The Abert Lake Petroglyphs (Smithsonian trinomial: 35LK475) are a prehistoric archaeological site in Lake County, Oregon, United States. Peoples of the Great Basin cultural tradition pecked the images onto two basaltic boulders near major game migration routes. They are believed to be connected with rituals related to hunting activities, and contribute to the larger understanding of subsistence patterns in the northern Great Basin. They were made within the last 10,000 years, but their age cannot be stated more precisely due to the difficulty of dating petroglyphs.
