The Eldred Rock Light is an historic octagonal lighthouse adjacent to Lynn Canal in Alaska.

[4] It is listed on the National Register of Historic Places as Eldred Rock Lighthouse.

A fourth-order Fresnel lens was placed in the lantern room, near the top of the fifty-six foot lighthouse, at a focal plane of ninety-one feet.

In view of Skagway's commercial importance, the United States Board of Light-Houses established four manned lighthouses in Lynn Canal between the years 1902 and 1906.

Commissioned in 1906, Eldred Rock Light Station was the last lighthouse constructed in Lynn Canal; the second station in Alaska with light and fog-signal apparatus and keepers' quarters combined in a single structure; and the first lighthouse in Alaska constructed with concrete.
