The Kodiak National Wildlife Refuge is a United States National Wildlife Refuge in the Kodiak Archipelago in southwestern Alaska, United States.

The refuge has only six native species of mammals: Kodiak bear, red fox, river otter, ermine, little brown bat and tundra vole.

The non-native mammals Sitka black-tailed deer, mountain goat, Roosevelt elk, caribou, marten, red squirrel, snowshoe hare, and beaver were introduced to the archipelago between the 1920s and 1950s and are now hunted and trapped.

[3] The climate of the refuge is that of southern Alaska, mild and rainy.

Many areas in the refuge are densely forested with Sitka spruce at lower elevations.
