Afognak Island State Park, State park on Afognak Island, Alaska.

Afognak Island State Park is a protected area on an island off Kodiak Island and contains old-growth Sitka spruce forests along with several bays along the northern coast. The park covers 75,047 acres and provides space for different forest and marine habitats.

The reserve was founded in 1892 as the Afognak Island Forest and Fish Culture Reserve to protect forests and fish stocks. In 1908 it was integrated into Chugach National Forest, which changed its administrative structure.

The park lies on the traditional territory of the Alutiiq (Sugpiaq) people of Afognak Island. In 1980 the Alaska Native Claims Settlement Act transferred the land to Native corporations, and in 1994 and 2001 acreage was sold back to the state as parkland. The park's name comes from Afognak Island, whose Alutiiq name is Afognak.

The area is accessible only by seaplane or boat from Kodiak and therefore requires time and planning to reach. Two rental cabins near Pillar Lake and Laura Lake are available for visitors who want to stay longer.

The park's boundaries enclose Perenosa, Seal and Tonki Bays, and it borders part of Kodiak National Wildlife Refuge to the west. Only a small section near Seal Bay was logged, in the 1990s, so most of the land remains old-growth Sitka spruce forest.
