Eosalmo is an extinct genus of ancient salmonid that lived during the Eocene epoch. The genus was first described in 1977 from fossils found in lacustrine deposits in Driftwood Canyon Provincial Park, near Smithers, British Columbia, Canada, leading to the specific epithet E. driftwoodensis. Fossils from this genus have also been found at sites in Princeton, British Columbia, the McAbee Fossil Beds in B.C., and Republic, Washington, USA.
