Steller sea lion are distributed across the North Pacific Ocean rim from northern Hokkaido, Japan, through the Kuril Islands, Okhotsk Sea, and Commander Islands in Russia, the Aleutian Islands, central Bering Sea, and southern coast of Alaska, and south to the Channel Islands off California. During the May-to-July breeding season, Steller sea lions congregate at more that 40 rookeries, where adult males defend territories, pups are born, and mating takes place. Non-reproductive animals congregate to rest at more than 200 haul-out sites where little or no breeding takes place. Sea lions continue to gather at both rookeries and haul-out sites outside of the breeding season.

The world population of Steller sea lions includes two stocks divided at 144° W longitude (Cape Suckling, just east of Prince William Sound, Alaska). The stock differentiation is based primarily on differences in mitochondrial DNA, but also on differing population trends in the two regions.
