The Dolly Varden trout (Salvelinus malma) is a species of salmonid native to cold-water tributaries of the Pacific Ocean in Asia and North America. It is in the genus Salvelinus of true chars, which includes 51 recognized species, the most prominent being the brook, lake and bull trout, as well as Arctic char. Although many populations are semi-anadromous, fluvial and lacustrine populations occur throughout its range. It is considered by taxonomists as part of the Salvelinus alpinus or Arctic char complex, as many populations of bull trout, Dolly Varden trout and Arctic char overlap.
